摘要
首先阐述了损伤理论中损伤变量的定义及其测定 ,并介绍了基本的损伤本构关系。然后通过对水泥土的弹塑性损伤试验 ,探讨了水泥土的损伤机制 ,并得到了一系列损伤关系曲线 ,为建立水泥土的弹塑性损伤模型奠定了基础。
There is obviously linear-elastic stage in the stress-strain curve of the cemented soil.A large plastic deformation will be occurred in a cemented soil relative to the concrete.Therefore,the cemented soil is regarded as a kind of material with an elasto-plastic property.In this paper,the definition and measurement of damage variable are given first.Then,a fundamental damage constitutive law is presented.Through the elasto-plastic damage tests of a cemented soil,the damage mechanism is studied.A series of damage relationship curves are obtained.This work is the foundation for the elasto-plastic damage model of the cemented soil
