摘要
对青藏铁路某简支T梁桥进行现场动载试验,得到该桥梁结构在列车通过时的动力响应;同时采用midas/civil软件建模对该桥进行动力学的有限元分析得到数值解,将实测值和计算值进行对比分析,判断了其承载力和工作性能,为桥梁的加固与否提供依据。
The scene dynamic load tests are carried out on the simply supported T beam bridge in Qinghai-Tibet railway,which studied the dynamic response of the bridge structure when the train running on it.And the model was established by midas/civil to get numerical solutions of the dynamic behaviors which were comparative analysised with the measured results in order to evaluate the carrying capacity of the bridge.It provides reference datas for bridge strengthening.
