基于污染场地模型的高密度电阻率法数值模拟分析
Numerical simulation analysis of high-density resistivity method based on contaminated site modeling
摘要
Abstract
With the accelerated industrial transformation and urbanization in China,the relocation of many chemical companies has left behind potentially polluted sites.The high-density resistivity method is increasingly important in investigating and monitoring polluted sites.However,due to the variety of device types,there are advantages and disadvantages to various devices,so choosing a reasonable and effective type of device is crucial to the effectiveness of the survey.Based on the common characteristics of contaminated sites,monolithic,horizontally parallel,vertically parallel,low-resistance shielding,stochastic distribution,and diffusion models of organic and inorganic contaminants in the subsurface strata were constructed using the high-density resistivity.Two-dimensional orthogonal simulations and inverse calculations were carried out by using three commonly used devices.Through comparison,it is found that for actual contaminated sites,the minimum recognizable contaminated body must be at least twice as large as the electrode distance,and the deeper the depth,the worse the recognition accuracy.Under specific conditions,the dipole-dipole device exploration effect is significantly better than that of other devices,especially for the lateral boundary of the anomaly body recognition accuracy,which is higher.The high-density resistivity simulation experiments carried out in this study have implications for surveying in contaminated sites,choosing which type of device to use,and improving the identification of anomalies by interpreters.关键词
