地球物理方法对垃圾填埋场探测的有效性试验研究

文中根据在河北省某市两处不同类型垃圾(建筑垃圾和生活垃圾)填埋场上采用多种地球物理方法(高密度电阻率法、探地雷达法、高精度磁测法、激发极化法和瞬变电磁法)进行试验研究所取得的实测资料,结合工作地区的地质和岩土物性特征,通过分析对比,指出了不同地球物理方法在圈定和监测垃圾填埋场的污染范围和扩散趋势等方面的作用和能力。实验证明,垃圾填埋场渗漏污染检测中,探地雷达法、高密度电阻率法、激发极化法和瞬变电磁法均有一定的效果。除高密度电阻率方法外,激发极化法在监测垃圾的污染范围和污染趋势、圈定污染程度方面,效果也很明显。

The application of geophysical methods to the analysis of landfill

In this study,we have conducted experimental research on different types of landfill including construction and household waste in a city of Hebei province by using various geophysical methods,such as high-density resistivity method,ground-penetrating radar method,high-precision magnetic measurement method,induced polarization method and the transient electromagnetic method.According to the measured data and combined with the geological and geotechnical characteristics of the working area,we point out the role and the capacity of different geophysics methods in delineating and monitoring the coverage and spreading trends of the pollution of a landfill.It has been found that the ground penetrating radar method,high density resistivity method,induced polarization method and transient electromagnetic method have some effects in detecting contamination leakage of a landfill.The experimental research shows that besides the high density resistivity method,the induced polarization method also has a good effect in monitoring the scope and trend of pollution and delineating the degree of contamination.
