独塔双边箱梁斜拉桥结构分析

Structural Analysis of Single Tower Double Box Girder Cable-stayed Bridge

以实际工程为背景,对2×120m跨独塔双边箱梁斜拉桥建模计算,并进行静力分析、结构动力特性研究、结构地震响应计算,结果表明,该桥主梁和主塔的刚度和强度均满足规范要求,且有一定的安全储备,可为同类型的斜拉桥设计提供参考。

Taking the actual engineering as the background,the modeling calculation of a single tower double box girder cable-stayed bridge with a span of 2×120m is carried out,and the static analysis is made.The structural dynamic characteristics are studied and the structural seismic response calculation is carried out.The results show that,the regularity and strength of the main girder and tower of the bridge meet the requirements,with certain safety margin,which can provide reference for the design of the same type of cable-stayed bridge.
