中文摘要：

为研究高密度电法对地下无机物污染液体渗漏监测的有效性，在野外进行了延时性高密度电法实验。在场地内采集浇盐水前和浇盐水后不同时刻的高密度电法数据，分析了视电阻率的时空变化特征。初步实验结果表明，延时性高密度电法对盐水溶液的扩散有很好的探测效果，揭示了延时性高密度电法这种新的地球物理方法将对无机类化学污染物的扩散、海水入侵、堤坝的渗漏、未饱和区域水的渗漏等工程地质和环境地质问题起到越来越重要的作用。

英文摘要：

In order to study the validity of the high-density resistivity method applied in monitoring the penetration of the inorganic solution, the field tests with the time-delay and high-density resistivity method were carried out. The high-density resistivity data were collected separately at different time before and after the ground was irrigated by using the NaCl solution, and the apparent resistivity at different space and time was analyzed. The preliminary test results show that the time-delay and high-density resistivity method has good effect in monitoring the salt water diffusion in soils, it reveals that the said method will play increasing important role for the prospecting of the engineering geological and the environment geological problems such as the inorganic chemical pollutants diffusion, the seawater intrusion, the leakage from dams and the flows of water through the vadose zones.
