Railway is an important infrastructure of the country and plays a key role in the comprehensive transportation system. Since the reform and opening up, China's railways have developed rapidly, accounting for only 7.2% of the world's railways and about 24% of the world's railways. However, China Railway still cannot meet the needs of national economic and social development, especially the passenger transport capacity between large and medium-sized cities is seriously insufficient. The construction plan of European passenger transport network is to connect the capitals of more than 20 countries first, which is very important to realize European economic development. According to the medium and long-term railway network planning, passenger dedicated lines should be developed between large and medium-sized cities as soon as possible, intercity railways should be developed in densely populated areas, and the rapid passenger transport network covering major cities in China should be accelerated.

2. Adhere to technical standards to ensure construction quality. The construction of China Passenger Dedicated Line should learn from the experience and lessons of other countries' rapid railway construction. On the basis of summarizing the railway construction work in China for many years, we should adopt a brand-new construction concept, a brand-new management system and a brand-new supervision mechanism, conscientiously implement the technical policy of "advanced, mature, economical, practical and reliable" and build a high-quality passenger dedicated line.

Change the concept and go all out to build a high-quality passenger dedicated line.

Over the years, we have become accustomed to the extensive construction mode of "quota design, deadline opening and status quo transfer". The loose combination of construction and transportation has brought many sequelae, and the construction of high-quality passenger dedicated lines must not return to this strange circle. In this sense, the success or failure of the construction of passenger dedicated lines depends on the construction concept, that is, whether we can change our concepts and do all the work well under the guidance of the leap-forward development idea put forward by the party group of the Ministry.

1. Overcoming existence is a reasonable concept and establishing the concept of keeping pace with the times.

We should be soberly aware that the contradiction that China's railway construction technical standards can't meet the needs of railway leap-forward development is prominent, especially the construction concept including design, construction and management is far from the requirements of passenger dedicated line construction. In addition, the speed target value of passenger dedicated line is not the same as that of passenger-freight common line. With the increase of train speed, the effects of various forces on infrastructure often increase geometrically, which is completely different from the traditional quasi-static design of railway. This requires us to keep pace with the times, abandon all old ideas and build passenger dedicated lines according to the idea of leap-forward development.

2. Overcome the concept of inaction and establish the concept that time waits for no one.

The target value of train speed on passenger dedicated line is relatively high, so whether it can achieve higher ride comfort is the key to its success, and the key to achieve higher ride comfort is whether it can effectively control foundation settlement. There is still a big gap in our understanding on this point. Even after taking the measures of replacing roads with bridges in soft soil areas, we are still pessimistic about settlement control. Whether the passenger dedicated line can be built well is related to the interests of the party and the country and to the development of the railway. The CPC Central Committee and the State Council entrusted the railway with this glorious and arduous task. We must stand on the height of practicing the "Theory of Three Represents", realizing the great rejuvenation of the Chinese nation, building a well-off society in an all-round way and realizing the leap-forward development of railways, understand and treat the passenger dedicated line project with a very strong sense of mission and urgency, and design, build and operate the rapid passenger transport network well.

3. Overcome the concept of professional division of labor and establish the concept of system theory.

The construction of dedicated passenger lines is not an isolated matter. We must use the thoughts and methods of system theory, comprehensively consider various elements, and realize their matching and optimal combination. From a big perspective, the rapid passenger transport network should be unified with the large system of nature and society, and the engineering design, engineering standards, technical equipment and operation management should meet the requirements of natural environment and economic and social development along the line; Unify with China railway network and realize the organic connection with existing lines; All kinds of facilities should be organically unified, and fixed equipment, mobile equipment and fixed and mobile equipment should be matched and coordinated to achieve the best combination; Design and construction should be unified with labor organizations and transportation organizations to create conditions for reducing staff and increasing efficiency. From the infrastructure itself, the unification of offline equipment and online equipment, and the guarantee effect of offline equipment on the fluency of online equipment; The structure of bridge and track is unified, and the performance and service life of each component in the structure are organically connected; Unify the service life of various facilities with the requirements of high-speed driving, and establish a high-quality and full-life security system; Unify the high reliability and low maintenance of all equipment, establish an efficient management system, and ensure the normal operation of equipment.

4. Overcome the concepts of equality, dependence and importance, and establish the concept of marketization.

The first-class concept can only be established in market-oriented operation, and the first-class quality can only be produced in competition. The brand left by the planned economy for many years is deeply rooted in the construction. So far, many work contents hope to undertake hereditary and technological monopoly. Although we have done a lot of work and achieved a lot of results in the technology of passenger dedicated lines, these achievements have been achieved through the competition and cooperation of all parties. In order to achieve the goal of building a high-quality and fast railway network, we must also implement the bidding system in scientific research, design, construction, material procurement and other links, conduct international bidding for many projects, adhere to the principles of openness, fairness and justice, and ensure the quality of design, construction and products.

5. Overcome the concept of big and complete, small and complete, and establish the concept of industrialized mass production.

The construction of rapid passenger transport network is a huge systematic project. Only by strict organization and scientific management can we do a good job in design and construction and adhere to specialization, standardization and rational production. From the beginning, according to the requirements of specialization, we should organize the most powerful experts in scientific research, design, manufacturing and construction in China to draw up unified technical conditions, concentrate on optimizing the most advanced scheme, and then determine the design unit and manufacturing unit through bidding to ensure the use of the best equipment in the construction of passenger dedicated lines. There are many similar projects. Although coordination is very difficult, it must be built in an industrialized way that conforms to the laws of modern railway construction in accordance with the requirements of modern enterprise management system.

6. Overcome the concept of one-sided emphasis on localization and establish the concept of using mature technology to form a late-comer advantage.

The introduction of advanced technology, joint design and production, and the localization of China brand are important ways for the development of science and technology in China, and also the policy that the railway has always adhered to for many years. It is inappropriate to emphasize localization unilaterally, even treat the introduction of advanced technology negatively in the name of protecting national industry, and oppose localization and imported technology. The development road of railway maintenance mechanization in China is the combination of technology and trade. Starting with the introduction of the most advanced equipment and technology in the world, relevant factories and scientific research units are organized to digest and absorb key technologies. The localization rate has gradually increased, and now it has reached more than 70%. Under the guidance of this policy, China's large-scale road maintenance machinery has developed rapidly. The 08-32 tamping car has produced more than 100 by itself, reaching the level of the original local machinery, meeting the needs of railway development and saving a lot of foreign exchange. At present, 09-32 tamping machine has been localized, providing more than 20 sets for the domestic market, greatly improving the equipment level of road maintenance machinery. Stabilizer car, ballast shaping car and screen cleaning car have also been successfully localized. If we go along the road of closing to the outside world, the road of highway maintenance mechanization in China will be delayed for at least 20 years.

7. Overcome the concept that rules apply to everything and establish the concept of taking full responsibility for quality.

Rules and regulations are the basis of our work, but in the process of implementing rules and regulations, we should proceed from reality and get satisfactory results because of different situations. For example, the minimum curve radius is a basic technical index in railway laws and regulations of various countries, but there is a world of difference between China and foreign countries when implementing this regulation. According to common sense, the minimum curve radius should be selected through detailed technical and economic comparison, which is also implemented abroad. But over the years, in order to save construction investment, we have used a large number of small radius curves regardless of the specific situation, which has brought great difficulties to the operation and caused a substantial increase in operating costs. A design that fully meets the regulatory requirements is not necessarily the best design. Regulation is the minimum requirement in design and must be optimized according to the actual situation. If you just apply the rules mechanically, it will often be counterproductive. The shortest slope length is widely used in the design of Qinhuangdao-Shenyang passenger dedicated line, which leads to frequent longitudinal collisions in train operation; The approach bridge of Wuhu Yangtze River Bridge adopts T-beam and light pier without transverse connection, which leads to the lateral amplitude of the bridge exceeding the limit and the long-term speed-limited operation. , and the design does not violate the specification requirements, but the operation practice proves that it is a failed design.

8. Overcome the task viewpoint and establish the concept of equipment life cycle.

Passenger dedicated line is an important national infrastructure, and the Ministry leaders clearly put forward that the service life of the main structure should reach 100 years. For many years, the requirement of durability has not been paid attention to in railway engineering in China. Generally, after the project is handed over, the design and engineering contractors will no longer bear the obligations and responsibilities related to environmental damage, restoration and reconstruction during use, resulting in insufficient durability and a large number of economic losses. 1998 "People's Republic of China (PRC) Building Law" and "Regulations on Quality Management of Construction Projects" issued by the State Council in 2000 all stipulate that the service life of building structures should be indicated. As an important industry in the national economy, railways should take the lead in implementing legal provisions, but in fact, railways are relatively backward in this regard. It is necessary to take the passenger dedicated line construction as an opportunity to introduce the concept of life cycle, formulate technical standards, strengthen quality control, and ensure the service life of the main structure 100 years.

Another aspect of establishing the concept of equipment life cycle is the construction quality. In the new line construction, due to the protection of the current handover policy, the phenomenon of poor construction quality is not uncommon. There are many common diseases such as false subgrade filling pressure, false bridge and tunnel foundation measurement, false smooth tunnel lining and mortar masonry. These low-level problems greatly reduce the service life of the equipment and seriously endanger the driving safety, so they must be completely eliminated in the construction of passenger dedicated lines.
