摘要
电测深作为一种常规的间接探测的地球物理勘查方法,主要是对勘查对象电性差异的反映,具有快速、经济、多解的特点。RGIS电测深反演解释的关键在于充分利用钻孔等已知地质资料,设置符合客观地质条件的地层及岩性(电性)参数,进而求取校正系数K。将电测深应用于卢氏县小岭山区某滑坡体的勘查,通过分析滑坡体的地质及地球物理特征,野外勘查采用电测深方法,充分了解勘查区的地质及电性特征,并结合钻孔资料,运用RGIS软件进行反演解释,推断出了滑坡体的分布范围及滑动带的空间分布特征。钻孔验证结果表明,电测深的推断解释结果与实际地质情况吻合较好。
As a regular indirect detecting geophysical exploration method with rapid and economic features and multiple solutions, elcclrical sound- ing mainly reflects different electrical properties of an exploratory object. The key of RGIS electrical sounding inversion interpretatinn makes utmost of the known geological data to set up strata and lithology parameters accordance with objective geological conditions, and to get cnrrection coeffi- cient K. Electrical sounding had been applied to a landslide mass exploration in a small hilly area of Lushi County. Complying with drill hole data, and with sufficient knowledge of geological and electrical characteristics of the explnration area, the inversion interpretation had applied RG1S soil- ware to infer distribution scope of the landslide mass and distribution feature of the sliding zone. The results show that the inferred eleclrical sound- ing interpretation coincides well with the actual geological conditions.
