悬索桥空缆线形计算

Analysis of Cable Shape of Suspension Bridge at Cable Finished Stage

系统地阐述了悬索桥空缆状态线形分析的数值分析法和非线性有限元分析法。通过对不同跨径悬索桥的分析,得出将数值分析法和非线性有限元法相结合的方法,既能快速求出悬索桥的空缆线形,又能在精度上满足工程的要求。

This paper expounds the numerical-analytical method and non-linear finite element method about how to analyze the cable shape of suspension bridge at cable finished stage. By analyzing many kinds of suspension bridges, a method is found. With proposed method we can find the cable shape of suspension bridge at cable-finished stage. The result meets the requirment of engineering, if the numerical-analytical method and non-linear finite element method are used together.
