| 摘 要： | 以主跨1 600 m的双塔三跨自锚式斜拉桥为基本研究对象,建立有限元分析模型,计算该跨径斜拉桥结构体系在恒载、活载、风荷载以及各种荷载组合下的结构静力响应情况。通过试设计方案的整体结构计算和参数分析,进一步摸清该跨径斜拉桥的静力力学特性,论述该跨径斜拉桥采用常规的双塔三跨自锚式全钢箱梁斜拉桥结构体系的技术可行性。

| Abstract: | The twin-tuwer three-span self-anchored cable-stayed bridge with main span of 1 600 m is taken as the basic study object. The finite element analysis model of the cable-stayed bridge system is built, and the structural static response is calculated in the condition of dead load, live load, wind load and various load combinations. Through the comprehensive structure calculation and parameter analysis of the preliminary design scheme, a variety of static mechanical properties of cable-stayed bridge with 1 600 m span are explained. At last, the technical feasibility of the conventional twin-towers three-span self-anchored cable-stayed bridge with steel box girder structure system is also discussed. |
