摘要

简要地介绍了次加载面理论的基本思想、假设及其物理解释。在广义塑性力学的框架内，引入次加载面的思想，把常规的椭圆-抛物线双屈服面模型，扩展为次加载面循环塑性模型，以反映循环荷载作用下土体的曼辛效应与棘轮效应。模型能考虑塑性应变增量对应力增量的相关性，既能反映土体的循环加载特性，又能反映正常固结土和超固结土的单调加载特性。

Abstract

The fundamental ideas and assumptions and their physical interpretations of subloading surface theory are presented. In order to describe the Massing effect and ratcheting effect of soils under cyclic loading

the conventional ellipse-parabola two-surface model is extended to the subloading surface cyclic plastic model by incorporating the Generalized plasticity and subloading surface theory. It is concluded that the model is capable of describing the deformation behavior of soil under monotonic and cyclic loading.
