| 摘 要： | 岩溶不仅会导致基岩面起伏很大，而且会产生较多的溶蚀带、溶洞、土洞等岩溶地质特征，灰岩分布区发生的地面塌陷等地质灾害，对建筑物安全及社会经济发展造成了严重的危害，高密度电阻率法是岩溶地质调查的重要物探手段。文章根据高密度电阻率法的基本原理及特点，对莱芜市泉河地区进行了岩溶地质勘查，通过对视电阻率二维成像图异常形态、高低阻等的反演分析，推断了该地区岩溶分布范围、大小和埋深。经钻探验证，推断结果与钻探资料吻合，为该地区岩溶塌陷地质灾害防治提供参考价值。

| Abstract: | Karst can produce large undulating surfaces , as well as other geological features such as dissolution belts, karst caves, and soil cavities, which can lead to geologic hazard affecting the security of buildings. This paper briefly introduces the basic theory and features of the high density Electrical Resistivity (ER) method which can be applied to exploration karst areas. Then a case study in Quanhe, Laiwu City is presented. Based on the interpretation of 2D image of the apparent ERs and their anomalies such as ER high and ER low , this paper infers the range, size and burial depth of karst in the study area, which accord with the results of exploratory drilling. The results of this work provide an important reference for the prevention and management of karst collapse geohazards in this region. |
