传统的土体本构模型大多是基于室内重塑土试验建立的。
The classical soil constitutive models almost were constituted by reconstituted soil in the lab tests.
土体本构模型一般都将土体作为各向同性材料,应用于混凝土面板堆石坝应力变形计算时常带来不小的误差,本文以双曲线模型为例剖析了计算中存在的问题。
In most of soil constitutive models, the soil is taken as isotropic material. This may result in significant error in stress and deformation computation for concrete slab in rock-fill dam.
利用土体的塑性流动理论,提出了用于描述饱和砂土在单调荷载作用下的应力—应变反应性质的弹塑性本构模型。
Based on the plastic flow theory of soils, an elastoplastic constitutive model for describing the stress-strain behavior of the saturated sands under the action of monotonic loading is developed.
