摘　　要：文中对某工程预应力闸墩及钢锚块建立ANSYS三维有限元模型,采用等效荷载法模拟预应力。计算中考虑了预应力闸墩与钢锚块的耦合效应,并通过在两者之间设置接触单元模拟预应力闸墩与钢锚块的接触非线性,重点分析了各计算工况下预应力闸墩混凝土结构的变形及应力。The ANSYS three-dimensional finite element model of prepressed gate pier and steel anchor block of some a project are built, and the prestress is simulated by the equivalent load method. The coupling effect between the prestressed gate pier and the steel anchor block is considered in the calculation, the deformation and stress of the concrete structure of the prestressed gate pier are analyzed emphatically in different conditions by setting up the contact unit to simulate the contact nonlinearity between the prestressed gate pier and the steel anchor block.

关 键 词：预应力闸墩 三维有限元 应力 接触非线性 等效荷载
