Homogenization-based investigation on constitutive relationship of oblique joint rock

It was suggested to employ asymptotic expansion-based homogenization method to establish the equivalent homogenized model of oblique joint rock.Macroscopic equivalent constitutive parameters of the model were predicted and compared with those given by other equivalent models.The numerical simulation of displacement of an underground cave was presented to verify the model in comparison with the results obtained by Goodman joint element-based FE analysis,and good accordance could be observed.
