| 摘 要： | 以某城市垃圾填埋场防渗帷幕为研究对象，采用高密度电阻率法、孔间声波透射法以及孔内电视成像等手段，借助多元回归分析方法，探讨地球物理无损检测结合钻孔探测在垃圾填埋库区防渗帷幕实体检测中的适用性。研究表明:高密度电阻率法因其快速高效，可实现对防渗帷幕的全面探查，圈定疑似质量缺陷区域。在此基础上，孔间声波透射法和孔内电视成像因其直观准确，可进一步判定缺陷具体形态、位置等，缩小处理范围。该综合检测方法通过多尺度搭配、多参数印证，可实现对防渗帷幕不同检测范围和精度要求的有效检测。

| Abstract: | The feasibility of the combining geophysical methods with borehole testing to examine the cut-off curtain at a city landfill site was discussed by adopting means of high-density resistivity method, cross-borehole ultrasonic transmission method and borehole television, in the inspection and resorting to multivariate regression in the analysis. The results indicated that high density resistivity method, with its high efficiency, could achieve an overall inspection of the cut-off curtain and delineated suspicious quality defect area. On this basis, cross-borehole ultrasonic transmission method and borehole television, which was intuitive and accurate, could be used to determine the specific characteristic and location of the defects, so as to narrow down the scope of reinforcing. Through multi-scale collocation and multi-parameter verification, this recommended comprehensive method could achieve effective inspection, with different requirements in testing scope and precision of the cut-off curtain. |
