沩水大桥为六孔38米预应力混凝土连续梁桥,全长240米,分为四孔一联和二孔一联。上部构造采用多点顶推法施工,为了减小顶推过程中箱梁的悬臂弯矩,采用在箱梁前端设置钢导梁方案。本文就导梁设计与施工的一些问题谈几点看法。
The Lishui Bridge is a six-hole 38-meter prestressed concrete continuous girder bridge with a total length of 240 meters and is divided into four holes and one hole and one hole. The upper structure is constructed by multi-point push-in method. In order to reduce the cantilever bending moment of the box girder in the jacking process, a steel guide beam is set at the front of the box girder. This article on the guide beam design and construction of some of the questions to talk about.
