索道桥成桥状态确定与安全性分析验证

Completion State Determination and Security Analysis on Cableway Bridge

以积石峡1#索道桥为例,通过理论计算,确定索道桥空索与竣工两种状态下矢度的施工控制重点,并分析索道桥主要受力构件悬索与锚索的安全性,比对荷载试验结果等方面论述,表明索道桥结构的可靠性。同时也为同类索道桥施工提供了借鉴参考。

Taking the No. 1 cableway bridge of Jishixia as an example,this paper determined the key points of construction control under the two conditions of empty and completed conditions of Cableway bridge through theoretical calculations; then analyzed the security of cable-stayed and anchor wire,which were the main stress components of cableway bridge,and compared the loading test results; finally the reliability of the cableway bridge structure is proved. Moreover,this research also provided reference for the same cableway bridge construction.
