摘要
本文所述工程实例开始设计应用视电阻率测深来探测工程区的岩溶裂隙发育情况。实际工作中,根据电阻率测深时各种参数的变化来进行综合资料解释,发现在测深时随着测量极距的变化而电位差未变这一反常现象,从而判断在该极距范围内为一等势体,改用充电法圈定等势体范围,很好地探明了工程区的岩熔裂隙发育情况。
The engineering in this paper case commences designing to apply apparent resistivity in detection of karst cracks developed. In actual works, an interpretation on comprehensive information is carried out according to a variety of parameters, it unveils the measured polar distances variance altered but electric potential difference is in stable when measuring the depth, consequently it is determined a equipotential body in a range of polar distance, the developed karst cavities were found perfectly by adopting method charging in defining distribution of equipotential body.
