摘　　要：以某现浇箱梁支架设计为例,对软弱地质条件下现浇箱梁桩柱式贝雷支架进行设计分析,采用MIDAS/CIVIL有限元结构分析软件建立支架空间杆系模型,合理模拟边界条件,准确添加施工过程中各项荷载,进行高仿真结构模拟分析,为软弱地质条件下现浇箱梁支架的设计与施工提供有效指导。In this paper,the stent of cast- in- place box girder is designed as an example. Schemes of designs on cast- in- place support used on wide box girder under weak geological condition are compared. To highly emulate the Structure simulation analysis,we use MIDAS / CIVIL finite element analysis software to establish the model of space truss,reasonably simulate boundary conditions and accurately add the construction process of the load. This provides effective guidance for the design and construction of the support of cast- in- place box girder under flabby geological condition.
