神农溪斜拉桥敏感性参数分析

以神农溪特斜拉桥为研究对象,运用桥梁结构计算软件桥梁博士,建立了计算模型。考虑主要设计参数变化,进行参数的敏感性分析,确定出影响主梁线形及索力的主要设计参数,分析结果可为施工控制提供参考。

Sensitivity Analysis of Structural Parameters of Shennong Cable-Stayed Bridge

Backgrounded by the Shennong Stream Cable-Stayed Bridge,established a bridge computational model by means of the bridge construction analysis program Dr.Bridge 3.0.Considering the main design parameters change and making the calculation and sensitivity analysis of various structural parameters of the bridge,the key structural parameters governing the main beam alignment and cable tension are determined.The conclusions provide reference to the construction control of the bridge.
