Some cement-soil samples measured in laboratory have showed low resistivity character in a short time after they were mixed. On base of this point
many electrodes were set on the top of cement-soil cut-off wall along it’s extend direction to detect the positions of different defects which had been set in the wall in a short time after it had been built. The measured apparent resistivity sections show depth of wall
blanks between poles and cement to soil ratio variation can bring apparent resistivity patterns change and their positions correspondence. Forward Calculated results with 2.5-D finite element method (FEM) also showed the same resisitivity abnormality character with field detecting results and the abnormal resisitivity patterns changing with the type
