摘　　要：通过实验发现 ,有限长边坡变厚式封面层的实际滑动面位置与无限长平行坡方法假定的滑动面不同 .按实验所得滑动面位置 ,推导出计算膨胀土路基边坡等厚式封面土层稳定性系数的公式 。Through laboratory study, it is found that the actual sliding surface occurred in veneer cover soil of variational thickness on finite slope is different from that of commonly used methods. According to the actual sliding surface from laboratory study, this paper develops a new formula for calculating the stability factor of veneer cover soil of variational thickness on the side slope of expansive soil subgrade. And some conclusions are also presented

关 键 词：封面土 边坡稳定性系数 膨胀土路基 滑动面位置 土工膜 抗滑稳定性系数
