扰动状态理论具有机理性与整体性的特征。根据岩土材料特性及使用者的需要,能够选用从简单的(线弹性的)到复杂的(具有微裂纹和扰动的粘弹塑性的)某一特定模型。本文介绍了扰动状态概念的基本概念,对国内外研究者基于扰动状态理论建立的本构模型研究进行了论述,概括了扰动状态理论模型的建模方法。研究成果表明:扰动状态概念不仅具有丰富的理论内涵,而且具有较高的工程实用性。它为工程材料提供了一种新的统一的本构模拟方法。
Disturbing state theory has the characteristics of mechanism and integrity. Depending on the characteristics of the geomaterials and the needs of the user, a particular model, from simple (linear elastic) to complex (viscoelasticity with microcracks and perturbations) can be used. In this paper, we introduce the basic conception of disturbance state, discuss the research of constitutive model established by domestic and foreign researchers based on disturbance state theory, and summarize the modeling method of disturbance state theory model. The research results show that the concept of disturbance state not only has rich theoretical connotation, but also has high engineering practicability. It provides a new unified constitutive modeling method for engineering materials.
