某变截面连续梁桥施工阶段及运营阶段结构分析

摘要

采用 MIDAS 分析软件，对某变截面连续梁桥施工阶段和运营阶段进行结构分析，总结此类桥型在两种状态下的受力模式，为类似桥梁工程建设提供借鉴。%This paper analyzes the structure stress of variable cross -section continual beam bridge during its construction and service stage using MIADS,summarize the bearing mode of these stage for this kind of brige ,to provide reference for similar bridge construction.
