桥梁静载试验方法研究

Study on Static Loading Test Method of Bridge

桥梁检测是保证桥梁结构安全的重要手段。在所有桥梁检测项目中,静载试验是了解结构特性的重要手段。结合某独塔斜拉桥静载试验的实际案例,介绍了斜拉桥静载试验的重点和方法,具体包括试验对象、工况设置及测试内容,静载试验的应变测点布置、挠度测点布置、主塔位移测点布置、索力测试,以及加载效率。该桥现阶段结构强度和刚度均满足规范要求,相关工程经验为以后该类型桥梁检测中的静载试验提供一些参考。

The bridge detection is an important method to guarantee the safety of bridge structure. The static loading test is an important method to understand the structure property in all bridge detection items. Combined with the practical case of static loading test for a simple-pylon cable-stayed bridge, the article introduces the essentials and methods of the static loading test for cable-stayed bridge mainly including the test object,operation setting and testing contents, strain detection point arrangement, deflection detection point arrangement,main pylon displacement detection point arrangement, cable force testing and loading efficiency. The structure strength and rigidity of this bridge all satisfy the standards and requirements at this stage. The relative engineering experience can be referred for the static loading tests in the detection of the similar bridges.
