根据大面积地质测绘分析,武广客运专线天子岭隧道下有大型地下暗河穿越,确定暗河平面位置、埋深及流量,对隧道设计、施工起着关键作用.勘察中运用测绘、物探、钻探、综合测井、地下水位长期观测等综合勘探方法分析,最终确定暗河主通道位于隧道出口段线路路肩以下10～15 m,雨季暗河涌水量达2.5 ×10~4 m~3/d,为隧道设计提供了可靠依据,并在工程施工中得到了验证.

By analyzing the large-area surveying and mapping of geology, there is a large-scale underground river under crossing Tianziling Tunnel of Wuhan-Guangzhou Passenger Special Line. It's very important to determine its plane position, embedded depth and discharge of underground river for the design and construction of Tiziling Tunnel. The comprehensive exploration methods were used in the investigation, that is, surveying and mapping of geology, geophysical prospecting, core drilling, comprehensive logging, long-term observations in ground water level etc. By analyzing the result of the comprehensive exploration, the underground river location was completely determined. The main channel, which crosses the tunnel under the 10 to 15 meters of the road shoulder of design line, is in the exit section of Tianziling Tunnel, and, the discharge is about 2.5×10~4 m~3/d in rainy season. The result provided reliable foundation for the tunnel design, and was verified well in the project construction.
