Three laboratory tests program were conducted in order to investigate the effect of double electrode fracture treatment on electroosmotic drainage.It shows that activated carbon treatment for crack is necessary and it can improve the discharge of moisture in soil increase the voltage of the soil at both end reduce the moisture content of soil and lower electrode corrosion. Only add activated carbon interlayer soil samples near the anode electroosmosis effect is better than that of poles are adding activated carbon in soil interlayer soil samples.
