南京集庆门大桥V形墩刚构施工技术

Construction Techniques for V-Shape Pier Rigid-Frame Structure of Jiqingmen Bridge in Nanjing

南京集庆门大桥为V形墩连续刚构。介绍该桥V形墩臂和V构合拢的施工方法,着重论述了方案的优选、V构合拢和临时水平预应力技术措施及其模拟计算方法。

The Jiqingmen Bridge in Nanjing is a prestressed concrete continuous rigid-frame structure with V-shape piers. In this paper, the construction methods for cantilevers of the V-shape piers and closure of V-shape structure are presented, and the selection of construction schemes, closure sequences of V-shape structure, temporary horizontal prestressing techniques and construction simulation calculation method are detailed.
