部分斜拉桥PC主梁的力学性能研究

Mechanical properties research of PC girder of cable- stayed bridge

依托重庆嘉悦大桥工程实例,对宽箱、大悬臂PC主梁的部分斜拉桥进行空间应力仿真分析,并介绍了该桥主梁节段缩尺模型试验的研究成果。从理论和实践上探讨了外倾式双索面部分斜拉桥的PC主梁的受力特性。

Relying on Chongqing Jiayue Bridge engineering example, simulation analysis of space stress of wide box, large cantilever PC girder cable - stayed bridge was conducted, and also, scale model test results of the bridge girder segment was introduced. From the theory and practice, the mechanical properties of PC girder of extraversion type double cable plane cable - stayed bridge was discussed.
