摘要：

An extended constitutive model is proposed to describe the four different behaviours of rock and soil. Four parameters of the extended constitutive model are calibrated according to the correlation coefficient between the behaviours described by the model and experimental data. Based on an analysis, a 'quasi-stress and quasi-strain' relation is proposed to describe the post-failure behaviour of rock and soil. Test results showed that the model is suitable for representing the behaviour of rock and soil and can be used as a reference for the virtual internal bond model, spring model, damage model, discrete element method, etc.
