摘　　要：加油站泄漏导致的土壤和地下水污染是城市地下污染的主要类型之一.泄漏发生后,对石油污染羽进行实时监测和精细刻画是准确确定渗漏点位置和评估污染程度的关键环节.为实现这一目标,我们在本文中设计了一种新型采集方式的三维井间电阻率层析成像技术,并通过应用实例评测、分析了该技术对污染羽的精细刻画与量化评价能力.研究表明,本文设计的监测技术对加油站微小渗漏形成的污染羽,二次重复渗漏形成的污染羽边界及地下水位变动导致的污染羽扩散过程具有良好的刻画能力;并且利用反演后的污染羽三维空间电阻率数据及含油量-电阻率模型可估算三维空间污染羽含油量和总泄漏量.论文还根据三维观测电阻率时序反演结果,基于分级概念构建了泄露程度判别标准.论文研究对推进地下有机物污染羽三维精细刻画技术研究具有重要作用.The soil and groundwater pollution caused by gas station leakage is one of the main types of urban underground pollution.The soil and groundwater pollution caused by gas station leaks is one of the main types of urban underground pollution.In order to achieve this goal,we design a new acquisition method of three-dimensional inter-well resistivity tomography in this paper,evaluate and analyze the ability of this technique to finely characterize and quantitatively evaluate the pollution plume through application examples.The study shows that the monitoring technology designed in this paper has good ability to portray the pollution plume formed by small leakage from gas stations,the boundary of the pollution plume formed by secondary repeated leakage,and the diffusion process of the pollution plume caused by the change of the groundwater level;and the inverted three-dimensional spatial resistivity data of the pollution plume and the oil content-resistivity model can be used to estimate the three-dimensional spatial oil content of the plume and the total leakage volume.Based on the time series inversion of the three-dimensional resistivity data,a leakage level criterion is constructed based on the concept of grading.The research paper plays an important role in promoting the three-dimensional fine characterization technology of underground organic matter pollution plumes.
