摘要
粤港澳大湾区非法填埋固废事件频发且类型多样,针对这类鉴定对象复杂且不确定因素较多的案件,本研究采用多频电磁仪(GEM-2)对大湾区某固废填埋地块进行探测,通过向地下同时发射 4 个频率电磁波,获取地表至特定深度范围内地下物质的电阻率特征,从而快速圈定固废填埋的位置和范围,同时采用钻探方法进行验证.结果显示,感应电磁法推断的固废填埋范围约 18 900 m2,其中A区和B区面积分别为 8 760 m2 和 10 140 m2,通过现场钻探,证实上述区域混填有市政污泥、生活垃圾、废矿渣 3 类固废,地下填埋厚度为 0.5～5.6 m,填埋面积约 24 460 m2,总填埋量为65 330 m3,感应电磁法在B区的测试结果与钻探方法接近.研究表明,感应电磁法在环境损害鉴定评估中具有较强的应用价值,将其与钻探方法结合使用有利于提高鉴定的效率和准确性,为今后此类案件鉴定提供技术参考.
Abstract
The incidents of illegal solid waste landfill in Guangdong-Hong Kong-Macao Greater Bay Area(GBA)are frequent and diverse.For such cases with complex identification objects and many uncertain factors,a multi-frequency electromagnetic instrument(GEM-2)was used to detect a plot of illegal solid waste landfill in the GBA.The resistivity characteristics of the underground materials from the surface to a specific depth were obtained by simultaneously transmitting four frequencies of electromagnetic waves,so as to quickly delineate the location and area of solid waste landfill,and the drilling survey method was used for verification at the same time.The results showed that the landfill range of solid waste was estimated to be 18 900 m2 by induction electromagnetic method,of which the landfill areas of Area A and Area B were 8 760 m2 and 10 140 m2 respectively.Through on-site drilling,it was confirmed that three types of solid waste such as sewsage sludge,household waste and slag were mixed landfill in this plot.The landfill thickness ranged from 0.5～5.6 m,and the distribution area was approximately 24 460 m2,and the total volume of solid waste was 65 330 m3.The test result of induction electromagnetic method in Area B was similar to that of drilling method.It showed that the induction electromagnetic method has considerable application value in identification and assessment of environmental damage,and its combination with the drilling methods will improve the efficiency and the accuracy of identification and assessment,and provide technical reference for identification and assessment of illegal solid waste landfill cases in the future.
