摘要
基于斜拉桥拉索的受力特点 ,提出一种索张力测定的新方法。文中研究了索张力传感器的测试机理 ,导出了传感器测力信号与索张力的关系。研究结果表明 :该测试方法能有效地消除支座条件、拉索自重及索抗弯刚度等因素对测力信号的影响 ,可实现斜拉桥张拉索受力的精确。
According to forced characteristics of cable on cable-stayed bridge,a new method determining cable tension is provided.Testing mechanism of the sensor is researched and the relation between test signal and tension is deduced.The research results demonstrate that the determining method can eliminate errors brought by pivot conditions and selfweight and bending stiffness of the cable and can realize high precision and shortcut testing for the cable on cable-stayed bridge.
