摘　　要：文中以引水涵洞为例,利用有限元软件建立三维有限元数值模型,通过两种工况对引水涵洞进行应力和位移分析。根据计算结果可知,在防洪工况和地震工况时,涵洞结构材料的抗拉强度均超出规范允许值,最终将导致涵洞结构失稳破坏。进而为类似工程设计提供一定参考。Taking a pumping station culvert as the case,a three-dimensional finite element simulation by using finite element software is established,in which the stress and displacement of the pumping station culvert under two working conditions are analysed.According to the calculation results,the tensile strength of the material exceeds the allowable value of the code when the culvert is in flood control condition and earthquake condition,which would eventually lead to the instability of the culvert structure.

关 键 词：引水涵洞 三维有限元模型 应力位移分析
