基于非局部化方法的边坡稳定性分析

应变局部化问题已经成为岩土力学研究的一个重要课题，边坡的稳定性分析必然要考虑这种应变局部化对边坡的稳定性影响。结合Bazant等的非局部化模型方法，将其推广应用到弹黏塑性本构模型中去，考虑两种正则化机制的耦合作用，并采用有限元方法结合滑面应力法对边坡的稳定性进行分析。将数值分析结果与极限平衡法和基于线弹性本构的滑面应力法结果进行了对比，从分析结果来看文中的计算结果是合理的，对实际工程具有一定的指导意义。

Slope stability analysis based on nonlocal method

Strain localization is a very important subject in rock and soil mechanics; the influence of strain localization on slope stability must be considered. Considering the combination of two kinds of regularization mechanisms, this paper applied the nonlocal model method to elasto-viscoplastic constitutive model, and carried out slope stability analysis based on finite element slip surface-stress method. The results of limit equilibrium method and slip surface-stress method based on linear elastic model were compared with the results from this paper’s method. The results show that the numerical result of this paper is rational and is instructive for engineering application.
