中兴大桥V型主塔竖转施工技术

Vertical Rotating Construction Technology of V-shaped Pylon of Zhongxing Bridge

摘要:

中兴大桥为一跨过江矮塔斜拉桥，V型钢结构主塔采用竖向转体施工。通过施工实例，主要介绍了竖转结构体系设计、结构验算、竖转施工等关键技术，为类似施工提供一些借鉴与参考。

Abstract:

Zhongxing Bridge is a one-span short-pylon cable-stayed bridge. The V-shaped steel structure of its main pylon is constructed by vertical rotation. Through a construction case, the key techniques of vertical rotating structural system design, structural checking computation and vertical rotating construction are mainly introduced, which provide some references for the similar constructions.
