| 摘 要： | 提出了一种考虑软土损伤和流变性质的粘弹-粘塑性损伤模型。结合堆栽预压加固软基实例，分别采用殷宗泽双屈服面模型、粘弹-粘塑性和粘弹-粘塑性损伤模型进行有限元分析。结果表明，用粘弹-粘塑性损伤模型计算的结果与实测值比较接近，说明在工程分析中同时考虑软土流变和损伤是必要的。

| Abstract: | A viscoelastic-viscoplastic-damage constitutive model considering damage and creep of soft soil is presented.Deformation of preloaded soft ground was calculated with the Yin's double yield surface model,the viscoelastic-viscoplastic model and the viscoelastic-viscoplastic damage model respectively.It's shown that the simulation results with viscoelastic-viscoplastic-damage model are closer to the in-situ measured data,so both damage and creep of soft soil must be considered in engineering analysis. |
