在役斜拉桥索力测试研究

Study of Cable Force Test of Cable-stayed Bridge under Service

该文以某在役斜拉桥为对象,通过对该斜拉索索力测试结果和理论计算结果的对比分析,推定该桥多年运营后斜拉索中留存的索力情况,判定是否要对该桥的斜拉索进行索力调整,以确保桥梁运营安全。

Taking a cable-stayed bridge under service as an example, and according to the contrast and analysis of the test result and theoretical calculation result of the stayed cable force, the article deduces the cable force conditions existing in the stayed cable of this bridge after many years of operation, and determines whether or not to adjust the cable force of the cable- stayed bridge so as to ensure the operation safety of this bridge.
