某公路大桥静载试验研究与分析

Research and analysis on static load test of a highway bridge

以某公路大桥为例,对桥梁静载实验的测定布置、加载工况以及静力试验数据的获取和分析进行了介绍。结果表明:该桥计算理论和设计方法满足规范要求,整体受力、整体刚度、裂缝宽度都满足要求,研究所采用的试验方法及取得的试验结果可供同类桥梁成桥试验参考。

Taking a highway bridge as an example,this paper introduced the measurement and arrangement of static load test,loading conditions and the acquisition and analysis of static test data. The results showed that the calculation theory and design method of the bridge met the code requirements,and the overall stress,overall stiffness and crack width met the requirements,the adopted test method and gained test results could be used as a reference for similar bridge completion test.
