摘　　要：天山南、北麓古老基岩山体与山前平原之间存在着由第三系组成的背斜。背斜是否阻水决定着山区与平原区的水力联系,具有重要的水文地质和工程地质意义。在新疆台兰河山前,规划的老龙口水库就位于古木别孜背斜北翼。为了查明水库渗漏和坝基渗漏问题,采用地球物理TEM电磁测深技术和激发极化法,结合工程地质钻探与压水试验资料,对台兰河山前古木别孜背斜隆起部位隐伏构造的延伸状况及阻水性进行了分析。The tertiary sedimentary anticline distributed along the sides between the Tianshan Mountain and piedmont plain. The water-block characteristics of the anticline decide the hydraulic connection between mountains and plains, and has great significance in both Hydrogeological and engineering geological. The Laolongkou reservoir is located at the outlet of Tailan River in Xinjiang. In order to find out the dam foundation seepage and reservoir leakage problems, extension status and water-blocking feature of Gumubiezi anticline was analyzed using the geophysical TEM electromagnetic sounding technique and induced polarization method, engineering geological survey data and borehole water pressure test data.
