| 英文摘要 | Unlike shallow rock, deeply buried rock presents significant brittle-ductile behaviour during the post-peak deformation process. This paper concerns the mechanical characteristics of stress-induced brittle-ductile behaviour of prismatic deeply buried marble. For this purpose, a series of triaxial compression tests were carried out on prismatic marble under different confining pressures, and then the strength, deformation and brittle-ductile characteristics of marble were analysed. A method for the two key parameters (beta and B-d) affecting pre-peak hardening rate and post-peak damage rate to control the brittle-ductile characteristics was proposed, and the exponential functional relationships between the key parameters (beta and B-d) and confining pressure were established. Thus, an elastoplastic damage constitutive relation was developed within the framework of thermodynamics, and it was implemented numerically based on a semi-implicit return mapping algorithm. In addition, sensitivity analysis of the key parameters beta and B-d on the influence of pre- and post-peak deformation and brittle-ductile behaviour of rock were also investigated. Furthermore, the numerical simulation results predicted by the proposed model were also compared with the experimental results. It is found that the proposed model can capture the stress-induced brittle-ductile behaviour of deeply buried rock. |
