摘　　要：对白鹤滩水电站超高拱坝的带电梯井结构的拱坝坝段采用线弹性有限元法进行计算。采用子模型法,先对大坝整体模型进行计算,得到接触面上的节点位移,再取电梯井坝段建立精细化子模型进行计算,并对井壁结构按照应力图形法进行配筋计算分析,并结合类似工程确定配筋方案,为工程施工图设计提供依据。Linear elastic finite element method is used to calculate the arch dam section of the electric ladder well structure of the ultra-high arch dam of Baihetan Hydropower Station.By using sub model method,this paper first calculates the overall model of the dam,obtains the node displacement on the contact surface,and then establishes a refined sub model for the elevator shaft dam section for calculation.The reinforcement calculation and analysis of the wellbore structure are carried out according to the stress graph method.Finally,it combines similar projects to determine the reinforcement scheme,providing a basis for the design of construction drawings.
