摘　　要：具有相对隔水作用的地层界面,对路堑边坡的稳定性有非常严重的影响。通过列举黄土地区常见的几种隔水层,叙述隔水界面上高含水率黄土夹层的形成原因和特性,结合山西某工程黄土路堑边坡实例,分析隔水界面对边坡稳定性的影响,可为黄土地区同类地质条件边坡工程提供参考。The relatively impermeable formation interface has severe impact on the cutting slope stability. Several common aquifuges in the loess area are listed in this paper to analyze reasons and features of the formation of loess intercalary strata with high moisture content on the impermeable formation interface. Combined with examples of loess cutting slope in a project in Shanxi, the influence of impermeable formation interface on the slope stability is analyzed, which can be a reference for slope engineering with similar geological conditions in the loess area.

关 键 词：地层界面 高含水率黄土夹层 临空面 边坡稳定性
