Abstract

A certain area complicated formation condition was taken as engineering research background. Dynamic effect coefficient was introduced to analyze moving loads of railway subgrade. Under the conditions of goaf and fault, the movement and deformation laws are analyzed by numerical simulation using software RFPA2D when high-speed train goes across. Four different railway location plans were chosen to get the most unfavorable railway location, and then further research about foundation reinforcement and fault grouting was carried out for the most unfavorable railway location. Finally, the best method of foundation treatment was obtained.
