摘要
以鄱阳湖特大桥 90 m+180 m+90 m连续梁拱桥施工为背景,概述了钢管拱拱肋安装施工工艺及安全质量保证措施,防止了钢管拱拱肋在运输过程中的端部变形,并通过精细化测量工作保证了钢管拱拱肋在安装过程中的安装精度.
Abstract
Based on the construction of 90 m+180 m+90 m continuous beam arch bridge of Poyang Lake Bridge,this paper summarizes the construction technology and safety and quality assurance measures of steel pipe arch rib installation,which prevents the deformation of the end of the steel pipe arch rib during transportation,and ensures the installation accuracy of the steel pipe arch rib in the installation process through fine measurement work.
