摘　　要：耿楼枢纽工作区内建筑物结构复杂,诸多因素存在不确定性,采用常规的工程手段很难对闸址区的渗流稳定性做出定量的评价。为此,选取几种不同的上下游水位差,利用大型非线性有限元软件ABAQUS分别建立3种工况下渗流稳定性分析的三维模型,通过不同工况下的闸址区渗流场的三维有限元模拟,对闸址区的渗流稳定性做出评价,从而指导工程施工及运营。The works in the project area of Genglou Complex all have complicated structures. It is difficult to make quantitative evaluation of seepage stability in dam area by conventional engineering methods due to uncertainties of many factors. 3D models are established by ABAQUS, the non-linear finite element software, to simulate the dam area seepage field under three kinds of operating conditions with variable U/S-D/S water level dif- ferences, based on which the seepage stability of dam area is evaluated, rendering guidance for project construction and operation.
