EK-Grouting 기법을 이용한 연약지반 개량에 관한 연구

Abstract

This study carried out a series of field scale test for estimating field application of electrokinetic grouting technologies which was new method to improve a shear strength in low permeable ground using electrokinetic phenomenon. For configuring field application effectively, various factors affecting the electrokinetic grouting method in bench scale test were used to design the field scale test. The test was conducted 3 kinds of condition such as electrode decomposition, electrokinetic injection and hybrid method. The cone penetration test was conducted to obtain the change of cone penetration resistance values of improved field ground during field test. After the sampling process which in the same point, the various geotechnical test, three axial compression test and standard consolidation test to analyze the origin of strength increase.
