云桂线营盘山隧道地质雷达与风枪探孔的对比分析

Comparative analysis of geological radar and drilling in the Yingpan mountain tunnel of Yungui railway

  • 摘要: 岩溶为云桂铁路营盘山隧道的主要不良地质,岩溶对施工及隧底的稳定性影响较大.该隧道洞身位于岩溶垂直渗流带内,岩溶发育,开挖后采用地质雷达及风枪探孔对隧底及周边岩溶进行探查,地质雷达能定性探测区段内隐伏岩溶的发育情况,探测深度较大,风枪探孔能针对物探异常情况,准确探查岩溶特征.地质雷达及风枪探孔各具特点,将2种探测方法配合使用,在该隧道底部岩溶探测中取得了很好的效果.

     

    Abstract: The Yingpan Mountain tunnel was in the vertical seepage belt of karst area.Because the karst disease was very developed, it was one of the main geological disasters of this tunnel, which had influenced on the safety of tunnel construction and stability of the tunnel bottom.After tunnel excavating,the geological radar and drilling of this tunnel was used to survey the character of karst development at the tunnel bottom and sidewall.Geological radar can qualitative detection in karst development section concealed, detecting depth is bigger.Drilling for geophysical anomalies can accurately detect situation karst features.Geological radar and Drilling with various characteristics, the two detection methods to cooperate to use, in the bottom of the tunnel karst exploration good results have been achieved.
