摘要
介绍了桥梁动载试验的主要内容、检测目地、检测依据等,桥梁动载试验是对桥梁结构工作状态进行直接测试的一种检定手段,它也是评定桥梁动力性能和判断桥梁结构实际承载力的重要指标之一,通过结合正安县洋渡桥动载试验,详细的分析了桥梁动载试验的技术要点,如:脉动试验、刹车试验、跑车试验等技术要点以及得到数据后的详细分析,为桥梁的动载试验提供了有价值技术指导。
This paper gives a description of the main items,testing purposes and basis of the bridge dynamic load test,which is a means of monitoring the bridge structure in the working state and determining the actual carrying capacity of the bridge structure and one of the important indicators of bridge dynamic performance.Based on the dynamic load test of Yang Du Bridge in Zhengan County,Guizhou province,the paper analyzes the technical points of dynamic load test,such as pulse test,brake test,run test,offering a valuable technical guidance about static load test of the bridge.
