摘　　要：针对悬臂模板施工过程安全问题,文中运用有限元软件Midas/Civil,建立悬臂模板施工架体有限元模型,分析主要构件变形、内力分布情况,并进行整体抗倾覆计算。结果表明悬臂模板系统各构件强度、刚度满足设计要求,整体抗倾覆验算结果符合标准,结合现场实测数据进行分析,验证了施工方法的可行性与适用性。Aiming at the safety problem of the cantilever formwork construction process,this paper uses the finite element software Midas/Civil to establish a finite element model of the cantilever formwork construction frame,analyzes the deformation and internal force distribution of the main components,and conducts the overall anti-overturning calculation.The results show that the strength and stiffness of each component of the cantilever formwork system meet the design requirements,and the overall anti-overturning check calculation results meet the standards.Combined with the analysis of the field measured data,the feasibility and applicability of the construction method are verified.
