摘要

把天然粘土的变形看作是由结构的破坏引起的。总的变形由结构性粘土的弹性变形、结构面的滑移塑性变形和结构体破损引起的的损伤塑性变形组成。把滑移屈服面看作可以扩大、旋转的运动硬化面

并作为边界面

通过内插塑性模量来描述滑移塑性变形。采用损伤边界面

通过规定加荷或反向加荷产生损伤变形

卸荷不产生损伤变形来描述损伤塑性变形。建立了结构性粘土的边界面砌块体模型

并用试验进行了验证。

Abstract

The deformation of natural clays is induced due to the damage of structure. The total deformation consists of 3 parts

i.e.elastic deformation of structure body. plastic deformation due to sliding in the structure plane and irrecoverable deformation due to crushing of structure body. The sliding yield surface is considered as isotropic hardening and rotating hardening bounding surface. The plastic modulus is interpolated using the ‘real stress’ and ‘image stress’ on the bouding surface. It is stipulated that damage deformation occurs under loading or inverse loading conditions rather than under unloading condition. The bounding surface masonry model is developed and verified using test data.
