摘要
文中采用电测深法对某地铁DK25+748-DK26+952段剖面上的地质体电性情况进行探测,得到各测点地表以下电阻率变化及分布情况,结合前期调查所得地质资料,建立相应岩溶发育地质模型,以此为平台解释电测深等值线图。分析得到的岩溶病害既满足地质体电阻率变化曲线规律,也满足岩溶发育地质规律,从而可以得到比单纯通过电阻率曲线解译岩溶病害更加准确的结果。
By detecting the electrical properties,with the method of The Electrical Sounding,of the geologic body of the profile from construction situ DK25+748 to DK26+952,it can be easily gained the variation and distribution of the electrical resistivity of the survey points.When the development of the karst hazard is analyzed,preliminary geological investigation data should be integrated to contribute to form the Geological Model of the Development of Karst topography,by which to account for the contour map got by the Method of The Electrical Sounding,thus making the result of the analysis not only consistent with the resistivity variance,but meet the geology rules of the development of karst topography.So,we can get more precise results than the explanation of the karst hazard only by resistivity curve.
