摘要: This paper reports the results from a comprehensive numerical study on effects of micro-parameters smooth joint model (SJM) macro-properties and associated failure modes synthetic rock masses (SRM) under uniaxial compression condition using three-dimensional discrete element method. Important mechanical geometrical SJM that show significant SRM are identified. Strong coupling found to exist between various important so eventual sample is result complicated interaction among these micro-parameters. A limitation current stress-dilatancy relation accounting for roughness effect also The presented in this valuable evaluation capability simulating predicting shear behavior masses, further improvement its full application real at laboratory or field scales.
