ABSTRACT: Rock masses are composed of discontinuities and intact rocks. Previous studies have shown that rock mass deformations include not only macroscopic behaviour, but also microcracks that initiate, propagate, connect macrocracks and finally induce rock failure. It is thus vital to incorporate geo-mechanical characteristics of rock joints and normal loading into rock joint deformation model. The complete stress-displacement surface model, CSDS, describes the full shear behavior of rock joints subjected to differential loads. In this study, the model is updated by proposing a procedural stepwise method to calibrate CSDS model and effectively represent full shear stress of loaded rock joints by considering geo-mechanical properties. In addition, the proposed method is used with the plane failure analysis to describe progressive shear stress of large-scale rock slides using monitoring deformation data. The updated calibration method is then validated by existing experimental data and a real case study. The results show trustworthy of the proposed model.
