系杆拱桥吊索索力的振动测试方法

Vibration Testing Tied-arch Bridge Cable Force Practical Methods

振动法测试系杆拱桥柔性吊索索力是桥梁建设及运营状态最为常用的测试方法。通过结合规范、实测等方法对振动法测试中涉及的关键参数—索的刚度、计算索长、边界条件以及自阵频率的测试等参数进行了综述,为精确确定索力提供参考。

Vibration Testing Flexible arch bridge crane cable tension is building and operating state of the bridge the most commonly used test methods.Through specification,the measured vibration method and other methods of key parameters involved in the test-the stiffness of cable,cable length calculation,boundary conditions and from the array parameters such as frequency of testing were reviewed,to facilitate the accurate determination of cable forces.
