矮塔斜拉桥施工阶段结构行为研究

Analysis of Extra-dosed Cable-stayed Bridge during the Construction Period

以一座双塔双索面矮塔斜拉桥为工程背景,应用Midas/Civil软件建立其空间模型对矮塔斜拉桥在施工阶段的变形及受力特点展开研究,得出矮塔斜拉桥在施工期的变形、主梁内力及应力状况,分析其特点,为矮塔斜拉桥的设计及施工控制提供参考。

A extra-dosed cable-stayed bridge with double tower and double cable plane was taken as an example for this study. The Midas/Civil software was used to create the model of the bridge so as to study its characteristics of deformation and internal force in construction period. The status of the internal force and stress of the beam, and the deformation of the bridge in construction period can be obtained. The result can offer reference for the design and construction control.
