In order to detect and monitor contaminated zone in soil ground, a resistivity-cone penetration technique was developed. The cone has 4 electrodes and can measure electrical potential of soils during it's penetration. To calculate resistivity from electrical potential, the relation was formulated.The laboratory and field experiments showed that the resistivity of soils reflects the type of soils, the concentration of electrolytes, the existence of oil in soils and structure of soils, because it is a function of electrical conductivity of the constituents, Under some assumptions, the resistivity-cone developed in this study can be used to;a) know soil type,b) detect contaminated zone with electrolytes or hydrocarbons, andc) monitor effects of remediation works,

为了探测和监测土壤中的污染带，提出了一种渗透-静力触探技术。锥体有4个电极，可以测量土壤在其渗透过程中的电位。本文提出了由电位计算电阻率的关系式，室内和野外试验表明，土壤电阻率是土壤组分电导率的函数，它反映了土壤的类型、电解质浓度、土壤中石油的存在和土壤的结构。a）了解土壤类型，B）检测电解质或碳氢化合物污染区域，以及c）监测修复工程的效果，
