摘要
考虑应力路径影响的土坡稳定分析法，以土的三维非线性弹性本构模型为基础，在土坡稳定分析中可考虑不同有效应力路径对土坡失稳的影响。该方法还可根据土坡最终达到的应变水平评价土坡稳定性。
Based on three dimensional model of nonlinear elastic constitutive for soils, an analysis method is proposed, in which the influence of stress paths on failure of slopes is taken into consideration. With this method, the effects of different effective stress paths on failure of slopes, as well as stability of slopes, can be estimated according to strain levels in slopes. The method can be further simplified to analyse two dimensional stabilities of slopes.
