摘要
基于高密度电阻率法的工作理论和特点,应用该方法的温纳装置和施伦贝尔装置对石灰岩地区的岩溶进行探测,获得视电阻率二维成像图.通过分析视电阻率二维成像图异常形态、高低阻等特征,推断出岩溶的分布范围、大小和埋深.结合钻探验证探讨了 2种装置探测的有效性,为后期治理岩溶等地质灾害提供参考.
Abstract
Based on the working theory and characteristics of the high density resistivity method,Wenner array and Schlumber array of the method are used to detect karst in limestone areas,obtained the apparent resistivity two-dimensional image maps,analysised the anomaly form of resistivity ratio 2D imaging drawing and high resistance of characteristic,the author deduced the distribution range,size and depth of the karst.Combined with drilling verification,the effectiveness of the two devices is discussed to provide a reference for the control of karst and other geological disasters in the later period.
