摘要
从分析岩溶在高密度电阻率法断面上的异常特征入手,对视电阻率异常进行分类研究,并对典型异常进行了钻探验证,从而建立了典型异常的解译标志。进而对高密度电阻率法异常的科学合理解释进行指导。根据视电阻率的异常特征对工作区内岩溶发育程度进行了分区,为江山市场地工程建设适宜性分区提供了科学依据。
Started with the unusual characteristics of high density resistivity section in karst, this paper studies the abnormality of resistivity, verifies the typical abnormality by drilling prospecting, and sets up explanatory indication of typical abnormality. And then, it guides how to explain the abnormality of high density resistivity scientifically. Based on the characteristics of abnormal resistivity, this paper divides karst developmental districts, and provides scientific basis for the suitable districts of engineering construction in Jiangshan City.
