Soil testing is used to predict strength characteristics of soils. On the other hand, the resistivity of soils changes during deformation and with the change in stress. Therefore, the resistivity measurement can be used to predict the failure of soils during construction and also the occurrence of the land slide. In this study, three embankments were made and loaded to measure the change in resistivity of the soil during deformation and failure. In this experiment, four stainless nails were used as electrodes. The result is summarized as below;1. the resistivity increases with the loading.2. the increase in resistivity can be divided into three patterns, i.e., elastic, plastic and sliding behaviors.It is known that the resistivity of soils is decreased by the seepage of heavy metal solution. In this study, multi-elements solution was infiltrated into sand layer and the change in resistivity was measured. The result shows that the change in resistivity is proportional to the concentration of heavy metals. When trichloroethylene (TCE) was used for the infiltration test, the resistivity of sand was increased. The resistivity was changed by 1 ppm TCE solution.The in-situ test technique using conductivity cones were theoretically established. Basically, three cones are used at the same time, and they are moved to other penetrating point after measurement. By this, the investigation area can be extended.

土工试验用于预测土壤的强度特性。另一方面，土的电阻率在变形过程中随着应力的变化而变化。因此，电阻率测量可以用来预测施工过程中土壤的破坏以及滑坡的发生。在这项研究中，制作了三个装置，并加载，以测量在变形和破坏过程中的土壤电阻率的变化。在该实验中，使用四个不锈钢钉作为电极。结果总结如下：1.电阻率随着负载而增加。电阻率的增加可以分为三种模式，即，重金属溶液的渗透会降低土壤的电阻率。在这项研究中，多元溶液渗透到砂层和电阻率的变化进行了测量。结果表明，电阻率的变化与重金属浓度成正比。当三氯乙烯（TCE）用于渗透试验时，砂的电阻率增加。用1ppm TCE溶液改变电阻率，从理论上建立了电导率锥原位测试技术。基本上，三个锥体同时使用，测量后将它们移动到其他穿透点。这样可以扩大调查范围。
