摘要：
Based on summarizing of the technical treatment measures of bridge-subgrade transition section at home and abroad, combined with the characteristics of bridge-subgrade transition section. this paper proposed the strengthen schemes of subgrade surface layer by using graded broken stone and subgrade bottom layer by using tamping soil cement pile. The dynamic analysis of wheel/rail system shows that the strengthen measures call meet the requirements of dynamic performance. The research of this paper provides scientific basis for the design of bridge-subgrade transition section of heavy haul railway.
