岩土损伤本构模型研究进展

损伤力学在岩土工程中的应用日益广泛,很多学者建立了一大批基于不同条件的、适合不同材料的、考虑不同环境影响的各式各样的岩土损伤本构模型。根据研究损伤的方法不同,本文将这些损伤本构模型大体分为三类:宏观损伤本构模型、细观损伤本构模型和统计损伤本构模型,并对其进行评述,指出了当前损伤本构模型研究存在的问题和发展趋势。

Research Development of the Constitutive Model for Geo-material Damage

The application of damage mechanics in geotechnical engineering is increasingly extensive.A lot of damage constitutive models of geo-ma- terial which based on different conditions,suitable for different materials and considering different environments have been established.According to the different methods for damage research,these damage models can be classified into three types:macroscopic damage constitutive model,meso- scopic damage constitutive model and statistical damage constitutive model.This paper reviewed and analyzed the problems in existing constitutive model and its development tendency.
