摘要
为提高岩溶发育区物探方法的高效及可靠性,采用综合物探方法,主要以高密度电阻率法调查浅部地层信息,以地震反射法弥补了深部信息的缺失,以地质雷达技术补充探测研究区域内民用建筑下的岩溶土洞情况。结合钻孔资料等地质调查结论进行分析,各方法所得结果相吻合。验证了综合物探方法探测结果的正确性,总结了研究区域溶(土)洞的分布情况,并按岩溶发育强度不同对塌陷区进行区分,为类似工程案例提供参考。
In order to improve efficiency and reliability of geophysical prospecting method in karst area,using comprehensive geophysical prospecting method such as investigation of shallow strata information with the high density resistivity method,supplement of deep information shorage with seismic reflection method and supplement of karst soil caves under civil buildings in research area with geological radar.The results of those methods are consistant with each other,including comparison of the geological survey such as terra dirill data.The validity of result about comprehensive geophysical prospecting method is verified.The distribution of karst caves(soil caves)in research area is summarized,and the subsidence areas are classified according to different karst development intensity.This method can provide reference for similar engineering cases.
