基于CGP模型的岩土材料应力-应变曲线拟合

Fitting stress-strain curve of geo-material based on CGP model

介绍了复杂性理论中的一个重要概念——涌现,同时介绍了一种用于研究复杂系统涌现行为的CGP(constrained generating procedure)模型方法。首次将涌现概念应用于岩土工程,提出基于CGP模型拟合岩土材料应力-应变曲线的新方法。通过算例,说明所提方法可对应力-应变曲线进行成功拟合。

Emergence, an important concept of complexity theory, is introduced. A method known as CGP (constrained generating Procedure) model for studying emergence in complex system is introduced too. Emergence concept is applied to geotechnical engineering for the first time; and a new methodology based on CGP model to fit the stress-strain curve of geo-material is proposed. An example is studied; and the results show that the proposed method can be applied to fitting the stress-strain curve successfully.
