Seepage field changes of ship‐lock slope of TGP under raining and percolation

Abstract

The unsteady changes of seepage field of slope of TGP shiplock under raining and percolation are anlyzed by saturated seepage model. The computation suggests that raining and percolation do have some effect on the seepage field of high slope，but they don’t lead to high pressure water head in the shallow slope and vicinity of vertical wall of shiplock for the existence of drainage holes. Therefore, raining and percolation have slight influence on the stability of high slope
