本文提出了具有两组屈服面的新的应力-应变关系模型。它可用于剪胀土,也可用于非剪胀土。用这种模型所作的有限元分析表明,对于许多实际问题这种模型都是适用的。
This paper presents a new stress-strain relationship model with two sets of yield surfaces. It can be used for dilatancy soils and non-dilatancy soils. Finite element analysis using this model shows that this model is suitable for many practical problems.
