摘　　要：将结构性粘土看作由结构体和结构面双重介质组成,其流变分为滑移流变和损伤流变.在堆砌体模型的基础上,采用过应力理论,建立了结构性粘土的流变模型.其模拟计算结果与试验结果较为吻合.It is assumed that the structured clay is composed of structural block and structural face, and that the total viscous deformation consists of sliding viscous deformation and damage viscous deformation. Based on a masonry model, a viscouselasticplastic model for structured clays was proposed by using overstress theory. The simulation results consist well with the experimental ones.
