摘要

基于中井的子负荷面本构关系模型，采用高精度的隐式应力积分算法，研究了平面应变试验中超固结粘土试样的变形局部化问题。模拟了不同的加载速度和边界约束条件，得到了超固结比为8的藤森粘土土体内部明显可见的X型剪切带和单一型剪切带。结果表明：土体的剪胀特性、孔隙水在土体内的移动规律以及边界约束条件对剪切带的形成和发展起着控制作用。

Abstract

The Nakai's sub-loading constitutive model are used to investigate shear band localization in plane strain model tests. Boundary condition and loading speed effects on the overconsolidated Fujinomori clay are investigated using the finite deformation theory for shear band localization. Two obvious shear band patterns are obtained. It is indicated that the dilatancy of the overconsolidated clay

migration of the pore water and boundary constraint control the initiation and propagation of the shear bands.
