摘　　要：对于非饱和土,其强度和稳定性受含水率的影响较大,电渗法是一种新兴的地基改良技术,能快速降低土体含水率,加速土体的排水与固结过程,进而改善其工程性质。本文通过设置6个初始含水率相同的电渗试验,研究电势值和电渗时间与水分迁移量的关系。试验结果表明,在同一初始含水率下,相同电渗时间内土体水分迁移量的大小与电势值无关;电势值一定时,试验土体的水分迁移量随电渗时间的延长而增大。For unsaturated soil,its strength and stability are greatly affected by the moisture content.Electroosmosis is an emerging foundation improvement technology that can quickly reduce the moisture content of the soil,accelerate the drainage and consolidation process of the soil,and thus improve its engineering properties.This paper studies the relationship between the potential value and the electroosmosis time and the amount of water migration by setting up 6 electroosmosis tests with the same initial moisture content.The test results show that under the same initial moisture content,the amount of soil water migration within the same electroosmosis time has nothing to do with the potential value;when the potential value is constant,the amount of water migration in the test soil increases with the extension of the electroosmosis time.
