摘　　要：在常张高速公路分别由页岩和灰岩填筑的两段填石路堤上进行原位抗剪强度试验,以推滑平衡分析法为理论基础,分别获取两段填石路堤的原位抗剪强度指标内摩擦角?和粘聚力c。在计算过程中提出4点基本假设,经过现场试验数据计算分析,论证了假设的成立和推滑平衡分析法应用于填石路堤的正确性,并通过比较得出灰岩作为材料使填石路堤边坡更为稳定的结论。This experiment was based on the embankment of the highway from Changde to Zhangjiajie, which used shale and limestone in its two sections separately. The shear strength indexes of φ and c were obtained for these two embankments, and they demonstrated the reliability of thrust and sliding equilibrium method used to analyze the stability of embankment.

关 键 词：填石路堤 原位抗剪 推滑平衡分析法 抗剪强度
