摘要
合龙方案是大跨度连续梁桥悬臂施工的关键步骤,工程后期合龙方案的变更将会对桥梁线形产生不良影响,借助有限元分析软件MIDAS分析方案变更对桥梁线形及合龙口高差的影响。
The girder joint schemes is the key step of continuous bridge construction.In engineering late,the changement of the girder joint schemes will have a negative impact on the bridge line.This article analysis and contrast vertical displacement and closure of the height difference which caused by originally girder joint schemes and changed girder joint schemes by applying the finite element analysis software M IDAS.
