应用EIS观测技术圈定垃圾填埋区范围
THE APPLICATION OF THE EIS DETECTING TECHNOLOGY TO DELINEATING THE LANDFILL AREA
【摘要】 应用电法成像观测(EIS)技术对北京通州某垃圾填埋场开展了面积性探测,并采用Quasi-Newton算法对EIS观测资料进行了反演,获取了地下介质电阻率的分布特征。在此基础上,对垃圾填埋范围进行了解释推断。钻孔结果表明,EIS解释结果较为准确地圈定了垃圾填埋的范围。
【Abstract】 Electrical imaging survey(EIS) was conducted in a refuse sanitary landfill in Tongzhou District of Beijing.By adopting quasi-Newton inversion algorithm,the authors implemented the inversion of EIS data and obtained the cross-sections of resistivity.Based on the results,the authors infer the filling limits of the refuse sanitary.It is shown that the inferred results are in good agreement with the borehole data.
