An evaluation method is presented for the effectiveness of horizontal/semi-horizontal drains to reduce ground-water pressures in soil slopes. A system of horizontal/semi-horizontal drains is commonly used to enhance the stability of slopes in which ground-water is the main cause of instability ; this is the usual case for almost all landslide slopes in Japan. Despite its quite frequent use, no design guidelines have been established. In this paper ground-water behavior is solved by the 3D-finite element saturated-unsaturated seepage analysis. One dimensional linear finite elements are incorporated into the 3D-finite element ground-water system to simulate the influence of the drains. An experiment was conducted on a model sandy ground in a metal tank in which perforated drainage pipes were installed. The observed results were compared with the numerical ones, and good agreements were obtained, indicating the usefulness of the proposed method.
