摘　　要：边坡失稳是一种严重的地质灾害,在详细的地质调查、分析基础上,对枇杷园边坡的破坏模式进行分析,利用Adina软件对边坡进行有限元计算,分析边坡的应力分布,根据强度折减法理论,对边坡稳定性安全系数进行计算,研究成果表明,边坡可能沿软弱夹层滑动,对边坡采取以抗滑桩加固措施进行了有限元计算,验证加固方法的有效性。Slope failure is a kind of serious geologic disaster. Based on the detailed geological survey and analy- sis, failure mode of Pipayuan slope was analyzed. Finite element calculation with Adina software for the slope was performed, stress distribution in the slope was analyzed. According to the Strength reduction method, the safety coefficient for slope stability was calculated. The results showed that the slope probably slide along the soft interlayer. The effectiveness was verified by the finite element calculation for the slope with anti - slide pile rein- forcement.
