京杭运河邳州高架桥主桥为双塔双面预应力混凝土斜拉桁架连续梁结构体系 ,采用分段分步浇筑并张拉预应力的施工方法 ,施工过程复杂 ,结构体系及构件受力多变。本文介绍了对主桥主桁架施工过程进行监测的结果及其分析
The main bridge of Beijing-Hangzhou Grand Canal Danzhou Viaduct is a double-faced prestressed concrete continuous truss girder system with double-sided prestressed concrete. The construction method is step by step and the prestressing method is used. The construction process is complicated and the structural system and components are subject to varying forces. This article describes the main bridge truss construction process monitoring results and analysis
