Does the subject want to ask "what does the inclination of the double-block ballast bed mean?" The inclination of ballast slab is to ensure the stability and stability of railway track in use. In railway track design, the inclination of ballast bed is usually 1%-3%, and the specific angle depends on the curve radius of railway track and the running speed of trains. When the railway track is curved, in order to make the train pass the curve smoothly, it is necessary to tilt the ballast board at the curve.
