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.

“无张力”界面的建模

摘要 讨论了接口建模的两种常用方法之间的差异。尽管非常相似,但当应用于典型的边值问题时,这两种不同的方法会导致质量和数量上截然不同的结果。这在承受一般载荷的条形基础的不排水承载能力方面得到了证明。最后,将两种方法的结果与观察到相似差异的常见分析承载力表达式进行比较。
