Soil Improvement Using Electroosmotic Method with the Injection of Saline Solution

摘要

To enhance effect of electroosmostic improvement and to shorten therntime of treatment, this research made use of interaction betweenrnchemical solution and soil particles under the influence of electric field,rnsuch as cation exchange, water adsorption, and particle cementation.rnThe elctroosmostic method with the injection of saline solution wasrndeveloped in this study. The results of this research showed that usingrnthe electroosmostic treatment with the injection of calcium chloridern(CaCl2) treatment for a period of 9 days, the undrained shear strength ofrnsoil increased averagely by 350% compared to the initial strength andrn120% compared to electroosmostic treatment without the injection ofrnsaline solution. However, after the electroosmostic treatment with therninjection of calcium chloride (CaCl2) treatment for a period of 1 day,rnthe undrained shear strength of soil near anode is 1.36 times comparedrnto electroosmostic treatment without the injection of saline solutionrntreated for a duration of 9 days. The elctroosmostic method with therninjection of saline solution can certainly enhance electroosmostic effectrnof improvement and shorten the time of treatment.
