以含水岩土为样本，研究了不同含水率、不同矿化度、不同压力、不同温度以及岩土层中重力水面的不等高度状态下岩土层电阻率的定量变化，实验表明，岩土介质电阻率与所含水的特性有十分密切的关系。该实验首次把地下水前兆与地电前兆作为一个整体，来研究二者之间内在联系，并分析其相关特征。
Taking hydrous rock and soil samples as samples, the quantitative changes of resistivity in rock and soil layers under different moisture content, different salinities, different pressures, different temperatures and gravitation surface water level unequal height were studied. The experiment shows that geotechnical soil The resistivity of the medium has a very close relationship with the properties of the water it contains. The experiment, for the first time, examines the intrinsic linkages between groundwater precursors and geoelectric precursors as a whole, and analyzes their relevant characteristics.
