摘　　要：电渗法可以使水向直流电的阴极渗流和排出,从而降低土料的含水量,而且电流产生的热量还可蒸发土料中的水分以降低其含水量。如果把阴极布置在土料下方,直流电渗在土壤水分重力渗流的基础上再作用电渗,两者叠加效果更为明显。采用不同电压和电极形式的电渗法降低土料含水量的试验,得到了电渗法降低土料含水量的一些规律。The electro-osmotic drainage can make the water flow toward the cathode of the direct current, then discharge from the cathode, thus lower the soil＇s water content. And the calories that electric current produced can evaporate moisture, so that can also lower the soil＇s water content. If the cathode is placed under the soil, the function of the direct current electro-osmotic drainage is on the foundation of natural flow by the gravitation of soil moisture to act on electro-osmotic drainage, the result is more obvious when both fold to add. The article describes the experiments of the electro-osmotic drainage with different volt- age and different electrode form to lower soil＇s water content, drawing some regulations on electro-osmotic drainage method to lower soil＇s water content.
