摘　　要：针对公路膨胀性土质与岩质相结合的路堑高边坡,通过对膨胀土(岩)边坡的工程地质勘察及相关土性及强度试验,依据其工程地质特性进行边坡设计,通过对高边坡的稳定分析,提出采取土钉+土工格室+土工膜+挡土墙的综合处治方案,介绍了方案的设计及施工要点。实践表明该方案能经济有效地处治膨胀性土质与岩质相结合路堑高边坡。Through engineering geological survey on expressway high cutting slope with the combination of expansive soil and rock and strength test performed,the slope design was carried out based on its engineering geological characteristics. According to the stable analysis of the high cutting slope,the comprehensive treatment plan with soil nail ＋ geo lattice room ＋ geo film ＋ retaining wall was put forward,of which the design and the construction points was introduced. Practice shows that this plan can efficiently treat the expansive soil combined with rock cutting slope.
