Abstract The physical model tests were performed to study the influence of pipe drainage system on soil permeability，groundwater level and slope residual downslide thrust. The test results verify that groundwater pipe drainage system in pebbly-clay slope can markedly improve the soil permeability，drawdown the groundwater level，therefore decrease the slope residual downslide thrust and increase the slope stability. It is pointed out that underground drainage engineering should be the main measure in pebbly-clay landslide control.
