Abstract
In-situ soil remediation mechanism through the vertical drains (VDs) is analyzed with numerical model as the error and complementary error function. Results from in-situ test and analysis indicate that the contaminant concentration ratio as initial one () increases as the radius ratio () increases from the injection well, and also increases as the depth ratio () increases from the top of contaminated area. The elapse time needed to attain 50% and 90% clean up level () increases as the radius ratio () and the depth ratio () increase. As above results, the procedure of soil flushing in contaminated area using vertical drains makes progress from the top of injection well to the bottom of extraction well.
