摘　　要：我国众多水库大坝坝体为土石坝结构,由于修建的时间较为久远,均出现了不同程度的损坏及安全隐患,因此近年来我国投入大量的人力物力对水库进行除险加固。根据某水库除险加固设计方案,基于振型分解法的理论,利用ANSYS有限元分析计算软件,对该水库设计的工作桥在地震荷载作用下的安全稳定性进行计算分析,探讨其除险加固设计方案的科学性、合理性,可为后续类似工程提供相应的经验参考。Many reservoir dams in my country are earth-rock dam structures.Due to the relatively long time of construction,damage and safety hazards have appeared to varying degrees.Therefore,in recent years,my country has invested a lot of manpower and material resources to strengthen reservoirs.According to a reservoir's danger-removing and strengthening design plan,based on the theory of mode decomposition method,using ANSYS finite element analysis and calculation software,the safety and stability of the working bridge designed for the reservoir under the action of seismic loads are calculated and analyzed,and its reinforcement is discussed The scientificity and rationality of the design scheme can provide corresponding experience reference for subsequent similar projects.
