摘　　要：利用电渗试验装置,进行阳极区添加氢氧化钠电渗加固与纯电渗加固软黏土地基的室内模型试验对比研究。试验过程中记录排水量、电流等指标,试验结束后检测土体抗剪强度、含水率。试验结果表明:阳极区添加氢氧化钠电渗加固软黏土地基比单独电渗作用下加固软黏土地基处理效果好;减缓阳极腐蚀,延长阳极使用寿命,可为工程应用提供借鉴。We conducted a comparative experimental study about adding sodium hydroxide in anodic zone and electro-osmosis alone tests on the soft clay using a electro-osmosis apparatus. We recorded the volume of drainage and the current in the process of test, and measured the vane shear strength and moisture content after the test. The results show that the treatment effect of adding sodium hydroxide in anodic zone is better than that of electro-osmosis alone, it can slow down the anodic corrosion and prolong the service life of the anode, which can provide reference for engineering application.
