摘要
为了解决地面岩溶塌陷引发的地质灾害问题,采用了高密度电阻率法进行探测,来解决此类问题。以湖南某地区地面塌陷为研究对象,运用高密度电阻率法来圈定岩溶裂隙所在位置,划分重点坍塌区域,查明塌陷区域的地质构造及地层岩性变化。通过这种勘探方法,在该区域内有效的圈定了72处岩溶裂隙发育区,6处裂隙发育区,4处断层控制点以及4处地层界线控制点,证实了高密度电阻率法在岩溶塌陷的可行性和有效性,可为地质灾害防治提供技术依据。
In order to solve the problem of geological disasters caused by ground karst collapse, the high-density resistivity method is used for detection to solve such problems. Taking ground collapse in a certain area of Hunan as the research object,the high-density resistivity method is used to delineate the location of karst fissures, delimit key collapse areas, and find out the geological structure and lithological changes in the collapsed area. Through this exploration method, 72 karst fissure development areas, 6 fissure development areas and 4 fault control points have been delineated for this area, which confirms the feasibility and effectiveness of the high-density resistivity method in karst collapse. It can be a geological disaster provide technical support for prevention and treatment.
