摘　　要：本文指出连续梁施工是目前应用于跨既定线路桥梁施工最为广泛的施工工艺。为此,本文以某高铁建设工程为例,针对该工程中横跨河流、高速公路的连续梁施工技术特点、主要技术标准等,分析探讨了连续梁现浇钢管支架施工、悬臂浇筑梁段施工,以及挂篮及模板施工等重点施工环节。本文旨在为类似工程施工工艺的制定提供参考。It is pointed out that continuous beam construction is the most widely used construction technology for bridge construction across established lines.Therefore,this paper takes a high-speed railway construction project as an example.According to the technical characteristics and main technical standards of continuous beam construction across rivers and expressways in this project,this paper analyzes and discusses the key construction links such as cast-in-place steel pipe support construction of continuous beam,cantilever pouring beam section construction,side span straight section construction,hanging basket and template construction.This paper aims to provide reference for the formulation of similar engineering construction technology.
