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.

Key words: cofferdam, cut-off wall, seepage, slope stability, earthquake
