　　从材料破坏机理与规律出发研究结构性土体工程的渐进破坏过程，是实际工程研究的重要方向。针对结构性土的变形特点和传统本构模型解决结构性土体工程渐进破坏过程的不足，采用作者以前提出的结构性土损伤本构模型对边坡工程算例的渐进破坏过程进行模拟分析。算例计算结果分析表明：边坡在破坏过程中会形成一个贯通剪切带，剪切带土体完全损伤；剪切带上方土体损伤相对较小，且有距离剪切带越远损伤越小的趋势；剪切带下方土体损伤也较小，主要因为开挖对其影响很小且处于稳定的坡体内。研究证明，运用结构性土损伤本构模型能较好地解决实际工程损伤破坏问题。

Starting the progressive failure process of structured soil engineering from the mechanism and laws of damaged ma?terial is an important study direction to practical engineering in the future. Aiming at the deformation characteristics of structured soils and the disadvantage of traditional constitutive model to solve the progressive failure process of structured soil engineering, this paper adopts the structured soil damage constitutive model proposed by Zhou Jia?wu previously to simulate and analyze the pro?gressive failure process of slope engineering examples. Results of example analysis show that:1)a run?through shear zone will be formed during the failure process in the slope,and the soil in shear zone will be damaged completely;2)the damage of the upper sliding soil of shear zone is relatively small,and the further the upper sliding soil is from the shear zone,the damage is smaller;3)the damage of the lower part of shear zone is also small,and the major reason is that the lower part exists in the stable slope and the excavation process has little influence on it. The research demonstrates that the damage constitutive model of structured soil can be used to solve the problem of practical engineering damage&failure well.
