| 摘 要： | 索塔锚固区是斜拉桥中的关键部位,是将一对斜拉索的局部集中力安全、均匀地传递到塔柱的重要受力构造.锚固区荷载大、空间小、构造复杂、传力路径多、应力分布不均匀、受力机理复杂.建立索塔锚固区三维有限元模型,对龙岩大道高架桥主桥(200 m+70 m+27 m+43 m独塔双索面斜拉桥)索塔锚固区受力性能进行了局部分析,为该桥...

| Abstract: | Cable tower anchorage zone is a key part for cable-stayed bridge,which is the important stress structure of transferring local concentrated stress from a couple of cables to pylon with safety and uniformity.And anchorage zone has these characters as follows: huge load,small space,complicated structure & stress mechanism,more ways to transfer force,stress distribution with non-uniformity.To build a cable tower anchorage zone 3D finite element model,the local stress analysis for the stress function of the mai... |
