摘　　要：介绍了秦沈客运专线不同填料路基面的动应力和动位移的测试方法,根据具体测试结果分析了路基面的动应力和动位移与车速的关系;并且针对不同填料的路基,进行了动力特性的比较研究;另外,将实测结果与《京沪高速铁路线桥隧站设计暂行规定》的设计值进行了比较。The testing methods of dynamic stress and dynamic displacement on the surface of Qinshen high-speed railway roadbed are described. Based on the results of the test, the relationships between dynamic stress and speed and between dynamic displacement and speed are analyzed. Dynamic characteristics of roadbeds with different kinds of filling materials are discussed. Furthermore, the testing results are compared with the design capacity of the temporary standard for high-speed railway of China
