桥梁静动载试验检测方法及实例分析

桥梁静动载试验是检验桥梁结构工作状态或实际承载能力的一种试验手段。该文综述桥梁静动载试验的试验目的、测试项目和注意事项。结合实例通过对跨线桥进行载荷试验,用有限元软件MIDAS对检测桥梁进行建模分析计算,与实测试验数据进行对比分析,对该跨线桥的实际承载力状态做出评定,所检验桥梁满足设计荷载作用下的运营要求,该文对同类型桥梁承载力验算具有一定参考价值。

Bridge static and dynamic load test is a test method to test the working state or actual bearing capacity of bridge structure.This paper summarizes the test purpose,test items and matters needing attention of bridge static and dynamic load test.Combined with an example,through the load test of the cross-line bridge,the finite element software MIDAS is used to model,analyze and calculate the tested bridge,compare with the measured test data,and evaluate the actual bearing capacity state of the cross-line bridge.The tested bridge meets the operation requirements under the design load.This paper has a certain reference value for the checking and calculation of the bearing capacity of the same type of bridge.
