摘　　要：为研究水闸地基防渗墙的不同工况对水闸地基渗流稳定性的影响,以某水闸地基为工程实际,利用岩土软件geo-slope中的seep/w模块,模拟分析了水闸地基防渗墙铺设深度不足及防渗墙出现缺陷等5种工况下水闸地基渗流场的分布规律。计算结果表明:防渗墙铺设深度不足会影响防渗墙下游侧渗流场,防渗墙出现缺陷也会影响地基土的渗流场,缺陷位置越低,对渗流场的影响越大。In order to study the influence of different working conditions of cutoff wall on the seepage stability of sluice foundation,the seep/W module of geo slope is used to simulate and analyze the distribution law of seepage field of sluice foundation under five working conditions,such as insufficient laying depth of cutoff wall and defect of cutoff wall.The calculation results show that the seepage field of the downstream side of the cutoff wall will be affected by the insufficient laying depth of the cutoff wall,and the seepage field of the foundation soil will also be affected by the defects of the cutoff wall.The lower the defect location is,the greater the impact on the seepage field will be.
