摘　　要：利用极限分析上限定理,在非关联流动法则下研究了加筋土边坡的稳定性问题。对非关联流动法则下的土体强度参数进行了修正,基于边坡旋转的破坏机构,计算了土体重力功率以及内部能量耗散,并推导了筋材的内能耗散方程。根据功率相等的基本原理,得到了加筋台阶边坡的上限解答。最后分析了不同加筋参数对边坡安全系数的影响规律。Based on limit analysis upper bound theorem, considering the non-associated flow rule, the stability of reinforced soil slope was studied. The strength parameter under non-associated flow rule was modified, on this basis, the gravity power and internal energy dissipation was calculated applying the rotating failure mechanism, and dissipation formula of for reinforced step-slope was obtained by the equality ence of geotextile parameter on slope safety factor was geotextile was derived as well. The upper solution of external and internal power. At last, the influ- also studied.
