PARAMETERS IDENTIFICATION OF CONSTITUTIVE MODEL FOR HETEROGENEOUS BRITTLE ROCK USING PSO-FLAC3D METHOD

摘要：

Numerical simulation result of failure process of brittle rock is strongly influenced by model parameters such as parameters of constitutive model and their heterogeneity.But it is very hard to determine reasonable model parameters by experiment.A new method was proposed for identification of model parameters based on particle swarm optimization algorithm combined with FLAC3D numerical method.The method was tested by modeling the brittle failure process of granite.The results showed that the method is feasible.
