摘　　要：采用对比试验方法研究电渗排水和真空排水降低填料含水率的效能.试验分析表明,电渗法在细粒土料中的排水效率显著高于真空排水法,在粗粒土料中两者的排水效率大体相当,但电渗耗电量远低于真空排水,这一结果有助于选择适当的土料含水率降低方案.Based on contrast experiments,this paper researches the efficiency of electro-osmosis and vacuum dewatering,two methods for water content decreasing of filler.Analysis of experiments indicates that the efficiency of dewatering by electro-osmosis is higher than that by vacuum dewatering in fine grained soil,and it＇s almost the same in coarse grained soil,but the electricity consumption by electro-osmosis is much less than that by vacuum dewatering.The conclusion given in this article may be helpful to choose proper scheme for decreasing water content.
