摘要
针对独塔混合梁斜拉桥的结构形式和受力特点,提出该类斜拉桥的索力优化目标函数和约束条件,并对其进行优化求解,进而确定合理的成桥索力,以满足工程实践的要求。
Aceording to the structural style and stress characteristics of hybrid cable-stayed bridge with single tower, the objective function and eonstraint eondition are proposed for optimization solution, and the reasonable dead load cable tension can be determined. In order to satvsfy the requirement of engineering practice.
