Abstract

Abstract

Rock is a collection of mineral particles and an important heterogeneous material. Understanding its mechanical characteristics plays an important role in guiding geotechnical engineering and mining. As a typical granular material, the proportion of particle size distribution in granular element body certainly affects the macroscopic mechanical behavior of rock. PCF2D software was used to simulate the mechanical characteristics of rock models with different proportions of the same granular material element body by setting the granular material element bodies with different volume proportions. The simulation results show that the proportion of particle elements has obvious influence on the mechanical characteristics of rock. In the simulation process, the proportion of large particles significantly affects the compressive strength of rocks. The higher the content of large particles is, the greater the compressive strength is. The proportion of fine particles affects the tensile strength of rocks. The higher the content of fine particles is, the greater the tensile strength will be; however, excessive fine particles will reduce the tensile strength of rocks. Considering the influence of fracture morphology in the process of rock mass compression, penetrating fractures are formed by rock model with particle proportions of 1:1:1, 5:2:3 and 7:2:1, while those of 1:2:7 and 3:2:5 fail to form penetrating fractures. Moreover, the higher the proportion of fine particles is, the higher the probability of high number of fractures is.
