Modelling of ‘no-tension’ interfaces 无拉力界面的模拟

Abstract: The differences between two common approaches to the modelling of interfaces are discussed. Though very similar, the two different approaches lead to rather different results, qualitatively as well as quantitatively, when applied to typical boundary value problems. This is demonstrated with respect to the undrained bearing capacity of a strip footing subjected to general loading. Finally, the results of the two approaches are compared to common analytical bearing capacity expressions where similar differences are observed.

Keywords: Undrained shear strength Interfaces No-tension

摘要：讨论了两种常见的界面建模方法之间的差异。尽管这两种方法非常相似，但当应用于典型的边值问题时，它们在质量和数量上导致了相当不同的结果。这一点在承受一般荷载的条形基础的无排水承载力方面得到了证明。最后，将两种方法的结果与常见的分析承载力表达式进行比较，观察到类似的差异。
