| Abstract: | Based on the current actual urban rail transit condition,it makes a comparison on the gravel ballast bed and overall ballast bed from three aspects of beam stress,foundation settlement,and prestressed concrete beam deflection,and points out that the ballast bed determination should be according to the geology and construction conditions of urban rail transit. |
