高密度电阻率法在白蚁巢穴探测中的应用

Application of high density resistivity method to detection of termite nest

本文介绍了高密度电阻率法探测白蚁巢穴的适用性和可行性,并对南京市大泉水库、马洼土坝可能存在白蚁巢穴侵害的区域进行了高密度电阻率法试验探测。两个工程均发现高阻异常区域,经开挖证实为白蚁巢穴,试验探测取得了较好的结果。

The applicability and feasibility of the detection of termite nest with the high density resistivity method are described herein and the possible areas under the infringement from the termite nest of Daquan Reservoir and Mawa Earthfill Dam in Nan-jing are experimentally detected by this method as well. From both the projects, the areas with high abnormal resistivities are found out and then confirmed to be the termite nests through excavation; which shows that a better result is got from the experimental detection concerned.
