摘要
本次研究选择某厂区的西侧,共3处滑坡和1处崩塌,由于滑坡群稳定性较差,会给厂区带来安全隐患。为尽快查明滑坡群地下电性情况,共布设了4条高密度电法剖面,采用温纳装置进行重叠探测,探测结果清晰地揭示了滑坡群浅部中高阻和深部低阻的电性分布特征,结合钻探资料可为滑坡群的防治提供可靠意见。高密度电法对于滑坡群电性探测是一种较为可靠的方法,可作为滑坡类地质灾害防治研究的有效手段之一。
In this study, three landslides and one collapse were selected on the west side of a factory, which would bring potential safety hazard to the factory due to the poor stability of the landslide group. In order to find out the underground electrical property of the landslide group as soon as possible, four high-density electrical profiles are laid, and the Wenner device is used for overlapping detection. The detection results clearly reveal the electrical property distribution characteristics of the upper middle high resistance and the lower low resistance of the landslide group. Combined with drilling information, it provides reliable suggestions for the prevention and control of the landslide group. High density electrical method is a more reliable method for electrical detection of landslide group, which can be used as a means of prevention and control of geological disasters such as landslide group.
