| 英文摘要 | This research presents a Weibull statistical grain-based model in two-dimensional Particle Flow Code (PFC2D) to describe the microstructural heterogeneity induced by grain shapes based on centroidal Voronoi tessellation technology. A consistent parameterization strategy based on macroscopically measured data of Qianjiang salt rock was implemented to determine the microparameters of the numerical model. Deformation response, strength characteristics as well as microcracking behavior are examined by varying heterogeneity of numerical specimens under uniaxial compression and compressive tests with various confining pressures. The simulated results indicate that the proposed model is capable of predicting the mechanical behavior of salt rock in the laboratory and numerical conclusions. |
