On Statistical Damage Constitutive Model for Rock Based on General Self-consistent Theory
摘要
Abstract
To disclose the influence of micro-crack interaction on rock damage,based on the general self-consistent theory of rock material damage effects,a rock damage constitutive model is established to reflect the full process of rock failure under loads.According to probability and statistics theory,the development of micro-crack density is explored in rock damage model.Then,the hierarchical pattern search,an effective parameter inversion analysis method,is used to determine the rock damage model parameters.And rock damage model and parameters determination method are verified combined with engineering examples.The results showed that the proposed damage constitutive model can reflect the actual interaction among micro-cracks based on general self-consistent theory in engineering.Model parameters determined by hierarchical pattern search are authentic and reliable,which can be applied in practical engineering.关键词
