摘　　要：运用高性能多通道并行数据采集分析系统,以及 BY-1 型动静态土压力传感器等测试手段,对动力分散型电力动车组在秦—沈客运专线山绥综合试验段某路涵过渡段的影响进行了试验研究。研究结果表明:动力分散型电力动车组所引起的动应力-应变比较稳定,这对于列车的高速运行是有利的;同时对路涵过渡段线路纵向上动应力-应变特征和变化趋势进行了分析。For the disperse impetus dynamoelectric locomotive groups (DIDLG), an experimental study on the dynamic stress-strain impacts of a roadbed-culvert transition section of Shan-Sui multiple tests section in Qin-Shen passenger transport special railway line was conducted by using the method of high capability multicenter parallel data collecting and analyzing system, BY-1 dynamic-static stress sensor, etc.. It is obtained, that the dynamic stress-strain caused by DIDLG is steady comparatively, which is very advantageous for the high speed run of train; In the meantime, the dynamic stress-strain characteristics and the change trend in the direction of railway line of roadbed-culvert transition section are analyzed.
