中文摘要：
基于含油污水管道渗漏形成土壤污染区的物性改变，利用高密度电阻率法、自然电位法、探地雷达的方法对污染区进行了探测，试图通过污染区的分布特征确定渗漏点的存在．基于异常区布设的钻孔取样分析资料显示，含油污水的侵入会引起地下粘土层的电阻率增高，随着侵入量的增大电阻率越大，相应的探测电剖面异常区表现为高阻特征；相应位置的自然电位曲线显示低电位特征，探地雷达图像则表现为低频，高幅的特征．基于异常区的分布特征可以确定渗漏点的分布位置．研究结果证实了地球物理方法对此类工业污水污染区探测的可行性．
英文摘要：
The physical properties of soil will vary when it has been contaminated by waste water with oil from the leakage position of pipeline. On the anlysis of this variation ,we surveyed the contaminated area using HDR method, Spontaneous Potential method, and GPR method, in order to detect the leakage positions of Underground Industrial Waste Water Pipeline. The analysis of drilling samples from contaminated area indicates that the invasion of sewage with oil will cause the increase of resistivity of clay, and the more the amount of invasion, the higher the resistivity. At the same time, the abnormal patters in HDR profile shows high resistivity; however, the characteristic show low potential in the corresponding Spontaneous Potential profile, and low frequency and high amplitude in GPR profiles. According to the distributive characteristic of abnormal, we can determine the position of leakage spot. The survey result confirmed that the geophysics method is feasible in detecting this kind of industrial sewage pollution problem.
