| 摘 要： | 某在建隧道地质情况复杂，开挖过程中，隧道底部出现溶洞，地下水发育，已完成的仰拱段可能存在岩溶分布。通过探地雷达的探测，分析该隧道段的典型波形图，确定出了该段隧道底部岩溶的分布情况，并通过钻探资料验证，两者基本一致，为隧道安全施工提供了保障。

| Abstract: | A tunnel under construction had such complex geological condition that, in the course of excavation, a karst cave was found at the tunnel bottom, ground water was developed, and there may be a distribution of karst in the completed invert segment. As a result of detection of ground penetrating radar, the typical waveform graph for this segment of tunnel was analyzed, thus the distribution of karst at the tunnel bottom was specified and then verified to be consistent with the drilling data, securing safety of the tunnel construction. |
