| 摘 要： | 在公路建设中，由于岩溶存在，又受荷载等因素影响，可能导致溶洞坍塌。以湖南省省道S322线嘉禾到宁远段为依托，对其下伏溶洞处理前后路基稳定性进行了数值计算，并进行了对比分析，探讨了不同顶板厚度对溶洞路基稳定性的影响。采用注浆与加铺混凝土盖板的综合加固法处理溶洞路基，取得了较好效果。

| Abstract: | During highway construction,karst,or influence of load and other factors,may lead to cave collapse.Based on Jiahe-Ningyuan Section of Provincial Highway S322,the stability of the highway karst cave embankment before and after treatment is analyzed by numerical computation and the influence of karst cave roof with different thicknesses on this embankment is discussed.Karst cave embankment is treated by grouting and overlaying of concrete cover plate is used for reinforcement,which has good effect. |

| Keywords: | karst cave stability numerical analysis thickness of the karst cave roof |
