摘要
根据桥址处的气象、水文、地质、地貌等建设条件,鱼嘴长江大桥采用主跨为616 m的悬索桥方案。根据建设条件进行总体设计,桥塔采用门式框架结构;南锚采用重力式锚碇,北锚采用三角框架式锚碇;主缆采用预制平行钢丝股法(PPWS)施工;主桥加劲梁为正交异性板流线型扁平钢箱梁;南引桥采用跨径35 m的等截面预应力混凝土连续箱梁,北引桥采用跨径56 m的等截面预应力混凝土连续刚构体系。北锚碇采用明挖基础施工;桥塔塔柱采用滑模法施工,桥塔横梁采用支架现浇施工;钢箱梁采用分段制造,吊装焊接成桥的方法施工。考虑水位变动因素合理安排工期,完成水下基础及钢箱梁施工。
In accordance with the construction conditions of the climate,hydrology,geology and topography at site,the suspension bridge type having a main span 616 m is chosen for Yuzui Changjiang River Bridge.The overall design of the Bridge has been carried out in compliance with the conditions as mentioned.The bridge towers are designed as the portal frame structures.The south anchorage is the gravity anchorage while the north anchorage is the triangle frame anchorage.The main cables are to be made by the PPWS meth...
