摘要
采用探地雷达进行隧道掌子面前方的地质超前预报,并配以孔内探头进行探测,在发现掌子面前方有异常结构面或异常体时对异常体进行准确定位,使预报的精度大大提高。文章还介绍雷达进行超前地质预报探测的现场工作方法,重点介绍孔内雷达的解释方法。
This article introduces the application of ground penetrating radar for prediction ahead on tunnelling face access, when discovering some abnormal structure frame on tunnelling face access, With more detecting by borehole radar,it can exact detect the location of abnormal structure frame and improve precision of prediction . This article also introduces some working methods of ground penetrating radar for prediction ahead in tunnel, mainly on the interpreting method by borehole radar.
