摘　　要：以三峡永久船闸混合式闸室墙为研究对象,考虑温度荷载、自重的作用,采用三维有限元法接触问题非线性仿真计算,分析衬砌墙、结构锚杆和岩体联合受力情况下的结构工作状态。对衬砌墙和重力墙之间是否设置水平分缝作了探讨,对设置过缝钢筋的利弊作了分析。This paper, with the mixed chamber wall of the permanent ship-lock of the Three Gorges Reservoir as the research target, adopts the contact non-linear three-dimensional finite element method to carry on the simulation computation by considering the temperature loads and the gravity load. It analyzes the structure working status of the lined wall,anchorage bars and rock under united pressure,discusses the affections of horizontal contraction joints between the lined walls and gravity walls and studies the reinforcement across contraction joints.

关 键 词：混凝土应力 张开度 锚杆应力 过缝钢筋
