摘　　要：公路滑坡是造成路基变形破坏的主要病害,严重影响公路的施工安全及运营安全。以甘肃省泾华高速公路某滑坡为研究对象,在对滑坡规模、特征、形成机制分析的基础上,综合地勘及现场调研资料判定滑坡为小型浅层滑坡,随后对滑坡的稳定性进行了定性、定量分析与评价,依据评价结果设计处治方案进行比选,从工程环保、占地等因素考虑,确定了减载+轻型支挡防护为主的设计处置方案,最后结合处置方案进一步提出了方案实施时的施工要点。Highway landslide is the main disease that causes the deformation and failure of subgrade,which seriously affects the construction safety and operation safety of highway.Taking a landslide of Jinghua Expressway in Gansu Province as the research object,based on the analysis of the scale,characteristics and formation mechanism of the landslide,the landslide is determined to be a small shallow landslide by comprehensive geological exploration and field investigation data.Then the stability of the landslide is qualitatively and quantitatively analyzed and evaluated.According to the evaluation results,the treatment schemes are compared and selected.Considering the factors of engineering environmental protection and land occupation,the design and disposal scheme of load reduction+light retaining protection is determined.Finally,combined with the disposal scheme,the construction points of the scheme implementation are further proposed.
