摘要
徐海路桥定位为一座兼具经济性与景观性的城市桥梁。通过桥位环境研究以及多种桥型方案的综合比选,该桥最终确定为连续梁拱组合桥,跨径布置为(45+80+45)m=170m,采用先梁后拱、主梁悬臂浇筑的施工方案,并进行了减隔震设计。对该桥总体设计、结构设计、施工方案、计算分析进行了介绍,并对该桥设计特点进行了总结。
Xuhai Road Bridge is oriented as an urban bridge with both economy and landscape. According to the environment study of bridge location and the comparison of many bridge type schemes, this bridge is finally defined as a continuous beam-arch combined bridge. Its span layout is (45+80+45) m = 170m. The construction scheme is the pre-beam post-arch and cantilever pouring method of the main beam with the design of seismic mitigation and isolation. This paper introduces the overall design, structural design, construction scheme and calculation analysis of this bridge, and summarizes the design characteristics of this bridge.
