软土具高含水量、高压缩性、高蠕变性、低渗透性、低强度等特点。近年来有学者提出真空预压－电渗法对软基进行处理，并在工程实践中得到了运用。真空预压－电渗法只能排出软土中部分弱结合水，工后沉降仍然较大，难于满足工程要求。针对该问题，有学者在真空预压－电渗的基础上加入少量盐溶液，即真空预压－电动法对软基进行处理，取得了较好的实验效果。该文以珠江三角洲地区软土为研究对象，通过真空预压－电渗法与真空预压－电动法（加入 Cacl2溶液）的对比试验，验证了真空预压－电动法在软基处理中的优越性，为该方法的应用提供一定的科学依据。

The soft soil contain high water content,high compressibility,high creep,low permeability and low strength.Recently,some researches have dealt with soft foundation using vacuum preloading-e-lectroosmosis method which can only discharge partial weakly bound water in soft soil,but the amount of post-construction settlement is still too much to meet the requirements of engineering.To solve this prob-lem,a small amount of salt solution was added on the basis of vacuum preloading-electroosmosis method, known as vacuum preloading-electrokinetics method,and achieved a better experiment result.The soft soil in the pearl river delta region was studied.The comparative test was used between vacuum preload-ing-electroosmosis method and vacuum preloading-electrokinetics method (adding Cacl2 solution)in soft ground treatment,and it came to a conclusion that vacuum preloading-electrokinetics method is at an ad-vantage when dealing with soft soil,which provided a scientific basis for applications of vacuum preload-ing-electrokinetics method.
