桥梁检测中的动静载试验研究

Research of Dynamic and Static Loading Test in Bridge Inspection

动静载试验是一种桥梁实际状况检验的重要方法,可科学准确地评定桥梁结构的承载能力。结合某特大桥检测的案例,从试验对象、动静载试验参数等方面,深入对动静载试验进行分析,介绍动静载试验内容,利用桥梁专业软件midas Civil建立有限元模型,进行静力分析,通过实际试验测量值和理论值做比较,分析桥梁的承载力和对桥梁综合评定。

The dynamic and static load test is an important method to inspect the practical situation of bridge,and can evaluate the bearing capacity of bridge structures scientifically and accurately.Combined with an inspection case of a super major bridge,this paper further analyzes the dynamic and static loading test,and introduces the dynamic and static loading test contents from the aspects of test object,static and dynamic loading test parameters,and etc.The finite element model is established by the professional software midasC ivil of bridge to carry out the static analysis.According to the comparison of the practical test measured value and the theoretical value,this paper analyzes the bearing capacity of bridge and comprehensively evaluates the bridge.
