| 摘 要： | 珠江黄埔大桥是珠江三角州经济区环形公路东环段中连接广州与番禺的一座特大型桥梁,在方案设计阶段辅航道为430m双塔单索面预应力砼斜拉桥。现代斜拉桥是多跨连续的柔性结构,不同的桥位条件需要不同的结构体系,以达到结构受力的最佳性能。因此,文中以珠江黄埔大桥辅航道斜拉桥方案设计为例,对其约束体系进行了计算分析,并提出了本桥的最佳体系结论。

| Abstract: | The Huangpu Bridge over Zhujiang River is a oversize bridge connecting Guangzhou and Panyu city. In the project design stage, the assist sea-route is a 430 meter tilted bridge with double tower and single cable surface stress. The modern tilted bridge is the mass continuous flexible structure, different location needs different structure system in order to obtain the best performance. Because of this reason, the article takes the design of false channel tilted haul bridge in Huangpu bridge as an example to analyze and calculate the constraint system and brings forward the optimum system of the bridge. |
