跨河全焊接空间曲线钢桁混凝土组合变截面连续梁桥施工要经历一个复杂的施工及结构体系转换过程,施工过程受到许多不确定性因素的影响,特别是对于钢桁梁的安装技术具有很高的要求,施工时要根据工程特点、施工进度、施工环境条件等通过各种方案对比选定合理的吊装设计方案,对吊装设备的选择、吊装参数、吊装顺序、测量定位及调整方法等进行优化。本文阐述了钢桁架组合梁桥吊装方案设计要点。
Cross-river welded space curve steel-truss concrete composite variable cross-section continuous girder bridge construction to go through a complex construction and structural system conversion process, the construction process is subject to many uncertainties, especially for the installation of steel truss girder technology is very High requirements, according to project characteristics, construction progress, construction environment conditions, etc. through a variety of programs compared to select a reasonable lifting design, lifting equipment selection, lifting parameters, lifting order, measurement and adjustment methods and so on optimization. This article elaborates the design points of the steel truss composite girder bridge hoisting plan.
