摘　　要：随着铁路建设的持续进行,对土地资源的占用日趋明显。为减少大型公共设施对土地资源的占用,大型高架车站在铁路建设中的使用越来越广泛,并带来了显著的经济效益和社会效益。根据站场规模的不同,进出站设置的道岔连续梁的规模设计不同。由于各地施工条件的差异,所采取的施工方法也存在一定的区别。本文从道岔连续梁施工中的关键工序着手,结合现场实际情况,对永清南站高架站特大桥道岔连续梁施工过程中的关键工序如基地处理、支架搭设、模板安装、钢筋安装、混凝土浇筑、预应力张拉、孔道压浆等展开论述,为今后类似桥梁的施工提供一点借鉴。With the continuous construction of railways,the occupation of land resources is becoming increasingly apparent.In order to reduce the occupation of land resources by large public facilities,the use of large elevated stations in railway construction is becoming increasingly widespread,bringing significant economic and social benefits.According to the different scale of the station,the scale design of the turnout continuous beams set up for entering and exiting the station varies.Due to differences in construction conditions across regions,there are also certain differences in the construction methods adopted.This article starts with the key processes in the construction of turnout continuous beams,and combines with the actual situation on site.It discusses the key processes in the construction of turnout continuous beams for the Yongqing South Station Elevated Station Extra Large Bridge,such as base treatment,bracket erection,formwork installation,steel bar installation,concrete pouring,prestressed tension,and duct grouting,providing some reference for the construction of similar bridges in the future.
