某水电站泄洪闸预应力闸墩的三维有限元分析

Three-dimensional finite element analysis of the pre-stressed gate pier of the sluice in one water power station

应用有限元软件ANSYS对某水电站泄洪闸预应力闸墩进行了非线性数值模拟,讨论了钢筋和混凝土的本构方程、破坏准则、预应力施加等问题,并对该闸墩在三种工况下的应力值解进行分析,指出利用ANSYS对预应力钢筋混凝土做有限元分析是可行的。

Bythe finite element software ANSYS, it does nonlinear numerical simulation to pre-stressed gate pier of the sluice in one water power station, discusses the constitutive equations, damage criterion and pre-stressing force application of the steel reinforcement and concrete, and does analysis toe the stress in three work condition, and points out the element analysis to the pre-stressed reinforced concrete is feasible.
