珠江黄埔大桥辅航道斜拉桥辅助墩设置分析

珠江黄埔大桥是珠江三角州经济区环形公路东环段连接广州与番禺的一座特大型桥梁,在设计阶段辅航道为430m双塔单索面预应力砼斜拉桥。对于斜拉桥结构的体系而言,辅助墩的设置与否不仅影响斜拉桥的施工安全,也关系到桥梁结构的受力性能及造价的经济性问题。因此,以珠江黄埔大桥辅航道斜拉桥设计为例,对其是否设置辅墩进行力学上的计算分析,并进行总结。

Settlement analysis of Huangpu Bridge's assist tilted sea-route pier

The Huangpu Bridge over Zhujiang River is an oversized bridge combining 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.For the tilted haul bridge,the settlement of the assist pier not only affects the construction safety,bust also relates the force performance of the structure and the economy of the cost.Therefore,it uses the Huangpu assist tilted sea-route design as a sample in order to analyze the settlement or non-settlement of the pier.
