| 摘 要： | 以一个特定工程为背景，数值分析研究了防渗墙深度对围堰渗流特性及边坡在地震条件下的稳定性的影响，并比较分析了封闭式防渗墙和悬挂式防渗墙条件下渗流特性和地震稳定性的差异。研究表明，封闭式防渗墙可以有效控制渗流场，并对边坡稳定产生积极影响。

| Abstract: | The effects of the cut-off wall depth on the cofferdam seepage characteristics and its slope stability under earthquake, are studied by using numerical analyis. And the seepage characteristics of the wall and its dynamic stability are compared with a certain depth of the cut-off wall-the closed type and any other depth of it. It is shown that the closed cut-off wall can significantly reduce hydraulic gradient; and hence, make benefit to slope stability. |
