| 摘 要： | 在碳酸盐岩地区修建高速公路，最主要的隐患是岩溶发育易引发路基不均匀沉降、路基滑动、地表塌陷等地质灾害。为了查找隐患，采用时域有限差分法模拟了地表起伏、覆盖层厚度变化、不同充填效果时溶洞在地质雷达剖面上的反映特征，据此指导工程实测。并以贵州高速公路的部分路段勘察为例，介绍了地质雷达在岩溶地区路基勘察中的运用，取得了良好的效果。

| Abstract: | When high-grade highway is built in Karst areas, the problem we have to confront is that Karst may trigger a differential settlement of subgrade, embankment sliding, surface subsidence and other geological disasters. In this paper, the features of Karst cave were simulated by finite different time domain（FDTD） method in GPR profile under different conditions. An exploration of some sections of GuiZhou highway was introduced as an example. |
