高密度电法在黄土滑坡勘察中的应用

摘要

To discuss the applicability of high density resistivity method in loess landslide exploration, taking Dujiagou Land-slide as an example, the stratum structure and buried depth of foundation rock mass surface in the slope area are detected by the method. The working principle, selection of field detection device, survey line layout and data analysis and interpretation are in-troduced in detail. The practice shows that this method is feasible in loess landslide exploration. The geological radar and core-drilling results verified the survey results.%为探讨高密度变电法在黄土地区滑坡勘察中的适用性,以陇东地区杜家沟黄土滑坡为例,利用高密度电法查明了该滑坡范围内的地层结构和基岩面埋深,以及落水洞分布情况. 对该方法的工作原理、野外探测装置类型的选择、测线布置及数据处理、资料分析与解释进行了详细的介绍. 实践表明,运用该方法对黄土滑坡进行勘察是可行的,其勘察结果经地质雷达钻孔取芯验证是可信的.
