地质雷达在恒山南北麓次级隐伏断层探测中的应用

On application of geological radar in detection of secondary blind fault at north and south sides of Hengshan Mountain

大西高铁在山西忻州下官院和山西朔州王化庄之间设置恒山隧道,为研究恒山南、北麓断裂及次级断裂活动对隧道安全的影响,在隧道进口下官院、出口王化庄用地质雷达对断裂进行探测,最终确定3个活动断层断点,为评价断裂活动对隧道地震危险性提供了基础性资料。

The paper indicates Hengshan Tunnel is located between Xiaguanyuan of Xinzhou City and Wanghuazhuang of Shuozhou along Datong-Xi’an Express Railway in Shanxi Province,detects the faults with the geological radar at Xiaguanyuan,the entrance of the Tunnel,and Wanghuazhuang,the exit of the Tunnel to research the faults at the north and south sides of Hengshan Mountain and the secondary fault activities on the tunnel safety,and provides the fundamental documents for evaluating the hazards caused by the fault activities on the earthquakes along the tunnel by identifying the 3 points of the faults.
