Verification of the CSDS Model in Estimating the Postpeak Behavior of Hard Rocks
Rockburst is a serious instability problem in Canadian deep underground excavations and is related to the postpeak behavior of hard and brittle rocks. Rockburst potential can be estimated by comparing the postpeak stiffness of the failed rock and the prepeak stiffness of the surrounding rock. Estimation of the postpeak behavior of hard and brittle rocks can help engineers evaluate and predict potential severe instabilities. The complete stress-displacement surface (CSDS) model is an analytical model (a constitutive model for rock joints) that estimates rockburst proneness. This paper aims to verify the application of the CSDS solution for estimating the postpeak curve (postpeak stiffness) in intact hard rocks by experimental results. To verify the model properties used in the model, different types of rock mechanics tests have been performed. The results show that the CSDS model can be used to estimate the postpeak behavior of medium to hard rocks.
