摘要
文章针对某大型桥梁实际加固修复焊接,利用独自开发的焊接变形分析系统软件,预测不同工艺和工况条件下大桥的应力和变形,获得不同条件下桥梁变形和应力的分布规律,确认该大型桥梁加固焊接施工方案的安全性.同时,该文为实际焊接工艺的优化提供了技术解决方案.
Abstract
In this paper,for the actual reinforcement and repair of a large-scale bridge,the self-devel-oped welding deformation analysis system software was used to analyze the welding stress and deform-ation of the bridge under different processes and working conditions.The distribution rule of the de-formation and stress of the bridge under different conditions is obtained,and the safety of the large-scale bridge reinforcement welding construction plan is confirmed.At the same time,this paper also provides technical solutions for the optimization of the actual welding process.
