| 摘 要： | 在南水北调西线一期工程玛柯河—贾曲段工程地质勘察过程中,充分利用地球物理资料,实现地质与地球物理的有机结合。依据区域地质条件、岩石电性特征和岩层的沉积环境,按电阻率的高低范围及变化特征将13 km长的CSAMT电阻率断面划分为4个不同部分进行解译,其中,断层破碎带的解释结果与野外岩石露头所反映的地质信息吻合较好。作为一项新物探技术,CSAMT法可为分析工程地质问题提供基础资料,具有较好的应用前景。

| Abstract: | According to the regional geology background,sedimentary rocks mode and condition,and physical features of rocks,the characteristics of CSAMT section of the first stage of the west route of the South-to-North Water Transfer Project are analyzed to explore the strata structure,fault and groundwater condition.The CSAMT section is classified into four fragments in length of the total surveying line,which is 13 kilometers long.Results of comprehensive exploration technology of geophysics answer for the geology information of rock outcrops to fault zone and crash belt,which are verified by drilling data.CSAMT is worth popularizing in engineering of long embedded tunnel. |
