【摘要】 斜拉桥施工过程中线型的控制对于桥梁能不能合拢及成桥后的受力状态是否合理具有重要意义,本文以潭江特大桥为工程背景,采用有限元分析软件midas civil对钢梁悬臂架设过程中存在的影响桥梁线型的索力、梁重、塔旁支架刚度和温度等的因素进行分析,为类似的大悬臂钢梁施工提供借鉴。更多还原

【Abstract】 The control of the linear during the construction process of the cable stayed bridge is of great significance to whether the bridge can be closed and whether the force is reasonable after completion of bridge. This paper takes the Tanjiang Bridge as the engineering background,the factors such as cable force,beam weight trestle stiffness and temperature which influence the linear of the bridge are analyzed by finite element analysis software,which can provide reference for the similar construction process.更多还原
