摘　　要：本文利用有限元软件Autobank对某Ⅶ级地震地区的进水闸工程建立了二维渗流有限元计算模型，对水闸的渗流稳定和抗滑稳定进行了分析，并将有限元分析结果与传统的公式计算结果进行了比较。分析表明：公式求解只能从宏观的角度判断水闸地基渗流的稳定。而利用有限元分析渗流计算能够从微观的领域分析地基内部每个结点单元的水头和渗透力，能够清晰的找出地基内部可能发生管涌或流土的区域，有效地改善闸基的渗透稳定性。This article studies by using finite element software Autobank entrance gate ofa Ⅷ earthquake region engineering two-dimensional seepage finite element calculation model is established, the seepage stability of the sluice and the stability against sliding are analyzed, and the finite element analysis results and the results were compared in the traditional formula. Analysis shows that the formula is only from the perspective of macro judgment foundation seepage stability of the gate, and the use of finite element analysis for seepage calculation can from inside the micro domain analysis foundation permeation, each node unit head and can clearly find out the foundation of internal piping may occur or flow of soil area, effectively improve the seepage stability of the sluice base.
