摘要
通过对两座桥梁振动测试结果的分析,发现列车编组对桥梁振动响应很有影响,且这一现象过去常常被忽略.本文详细研究了列车编组与桥梁横向振动响应之间的关系,同时还就一座桥梁加固后的试验结果进行分析,指出用改善列车编组的方法提高桥梁动态性能的必要性和可行性.
By examining the test results of vibration for a few bridges, it is found that train formation has a strong effect on bridge vibration responses. The relationship between train formation and bridge vibration responses is researched in detail in this paper. By analyzing the test results of a reinforced bridge, it is pointed out that enhancing the dynamic performances of the bridge, improve train formation is also a feasible way.
