重庆寸滩长江大桥主桥为250m+880m+250m的单跨简支钢箱梁悬索桥。该桥设2根主缆,主缆采用预制平行高强钢丝索股结构。全桥共布置57对吊索,吊索采用预制平行钢丝束,与索夹采用销接式连接方式。主索鞍为全铸式结构,鞍底设置座板作为滑动副。散索鞍为底座式结构,底部设置柱面钢支座。主缆锚固系统采用型钢锚固系统。加劲梁采用流线型扁平式封闭钢箱梁,梁高3.5m,宽42m。南、北锚碇均为重力式锚碇,现浇扩大基础,锚体在平面均呈U形。桥塔为钢筋混凝土门式框架结构,两塔柱竖直布置,基础为分离式承台桩基础。
The main bridge of Chongqing Cuntan Yangtze River Bridge is a single span simple supported steel box girder suspension bridge with 250m + 880m + 250m. The bridge is provided with two main cables, the main cable using prefabricated parallel high-strength steel cable strand structure. The bridge is arranged 57 pairs of slings, slings using prefabricated parallel wire bundle, and the cable clip with pin-connected connection. The main cable saddle is an all-cast structure, and the saddle is provided with a seat plate as a sliding pair. Bulk saddle is a base structure, the bottom of the cylindrical steel bearings set. Main cable anchoring system uses steel anchoring system. Bending beam using streamline flat closed steel box girder, beam height 3.5m, width 42m. South and North Anchorage are gravitational Anchorage, cast-in-place to expand the foundation, the anchor body was U-shaped in the plane. The pylon is a reinforced concrete portal frame structure, with two pylons vertically arranged and based on a separate cap pile foundation.
