摘　　要：通过国内数座大型桥梁的施工塌陷事故及原因的分析,提出对大型桥梁施工过程中的力学计算问题应考虑的主要问题(施工阶段力学计算的不确定性、支架拆除顺序、结构体系转换、准确选定荷载组合分析结构内力和局部应力),以及在施工监控中应该加强和进一步提高的方向,从而避免施工事故的出现.In this paper,based on analysis the collapse accidents and their reasons for several largescale bridge in construction,the major problems（the uncertainty of mechanical calculations,structural system conversions,selecting load combination accurately）should be considered for construction of large bridges in the process of the mechanical calculating.The directions of further improvement were proposed during the construction monitoring,these are used of reference for counterparts in the design,construction and construction monitoring,in order to avoid the construction incidents.
