载荷试验在太行山高速公路桥梁检测中的实际应用

Practical Application of Load Test in Bridge Detection of Taihang Mountain Expressway

桥梁荷载检测试验是为工作人员提供科学评价桥梁承载能力的依据,同时也是安全检测的重要保障。以太行山高速公路邢台段工程某主线桥为研究对象,主要研究了静载试验数据的测试方式、应力值、数据处理及测试流程,从而评价试验桥跨承载能力以及设计荷载等级的使用要求;通过动载试验主跨自振频率以及冲击系数,分析桥跨结构的动力性能。

The bridge load test is a basis for the staff to scientifically evaluate the bearing capacity of the bridge,and it is also an important guarantee for safety testing.This paper takes a main line bridge of Xingtai section of Taihang Mountain Expressway as the research object,mainly studies the test method,stress value,data processing and test flow of static load test data,so as to evaluate the test capacity of the test bridge and the design load level.Through the dynamic test of the main span of the main span and the impact coefficient,the dynamic performance of the bridge span structure is analyzed.
