摘　　要：边坡稳定性分析是边坡安全评估和加固的理论依据,针对多米诺骨牌分析方法只考虑了条块底面滑移剪切破坏的不足,提出了考虑边坡发生倾倒破坏形式的多米诺骨牌分析方法。给出了多米诺骨牌模型在倾倒破坏假设下的计算方法和求解步骤,并提出了边坡发生倾倒破坏、滑移破坏和倾倒与滑移混合破坏的判别方法。通过研究倾倒破坏模式的多米诺骨牌模型,进一步完善和推进了边坡稳定性分析方法的理论及其在边坡工程中的应用。Slope stability analysis is the theoretical basis for slope safety assessment and stabilization.The inadequacy of the domino analysis method only considers the sliding shear failure of the bottom surface of the strip,and a domino analysis method considering the form of toppling failure of the slope is proposed.In this study,the calculation method and solution steps of the domino model under the assumption of toppling failure are given,and the discriminant method for toppling failure,sliding shear failure and mixed toppling and sliding shear failure of slope is proposed.The theory of domino analysis method for slope stability and its application in slope engineering are further refined and promoted by investigating the slope stability of domino model under toppling failure mode.
