大跨度拱桥吊杆索力的测试研究

Research on Test of Suspender Cable Force ofLong-span Arch Bridge

摘要:

以某一大跨度拱桥吊杆索力的测试为例，介绍了吊杆索力测试方法，并在频率法测索力的基础上，统一用一个吊杆计算长度的修正值进行实测索力的修正。结果表明：此法简单可靠，可为类似拱桥索力测量提供借鉴作用。

Abstract:

Taking the test of suspender cable force of a long span arch bridge as an example, this paper introduces the test methods of suspender cable force, and on the basis of measuring cable force with frequency method, a unified correction value of the calculated length of a suspender is used to correct the measured cable force. The results show that: this method is simple and reliable, and can be used for reference for the cable force measurement of similar arch bridges.
