摘　　要：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。In the experiment, sand with water was used as sample. The quantitative change ofthe sample resistivity was studied under the different height of gravity water, the differ-ent saturation degree, different mineralized degree and different pressure. The experi-ment shows that the medium's resistivity of the sample has a very close relation with thecharacteristic of the water in it. The experiment is the first one to take the precursors ofunderground fluid and geoelectricity as a whole to study the internal relations betweenthem, and to analyse the correlative characteristics.
