摘　　要：与传统矿山岩体力学实验教学手段相比,UDEC离散元数值仿真方法可以精确描述矿山岩体内部的各向异性和非均质性构造,直观、深入、可重复地研究应力扰动下矿山岩体破坏过程中的能量、应力、位移、裂隙演化规律,进而揭示矿山岩体破裂机理,可操作性较强、学生容易领悟,且省时省力、成本较低。文章采用UDEC软件研究了矿山岩体单轴压缩力学特性和破裂过程,揭示了单轴压缩条件下矿山岩体破裂机理。结果表明,将UDEC数值模拟方法应用于矿山岩体力学实验教学是完全可行的,可以提升学生学习研究矿山岩体力学的兴趣,提升主观能动性和创新能力。Compared with the traditional experimental teaching method of mine rock mass mechanics, the UDEC discrete element numerical simulation method can accurately describe the anisotropic and heterogeneous structure of mine rock mass, and intuitively, deeply and repeatedly study the evolution law of energy, stress, displacement and crack in the failure process of mine rock mass under stress disturbance, and then reveal the fracture mechanism of mine rock mass. This method is more operable, easy for students to understand, time-saving and labor-saving with low cost. In this paper, the mechanical characteristics and fracture process of mine rock mass under uniaxial compression are studied by using UDEC software, and the fracture mechanism of mine rock mass under uniaxial compression is revealed. The results show that it is completely feasible to apply UDEC numerical simulation method to the experimental teaching of mine rock mass mechanics, which can improve students’ interest in learning and studying mine rock mass mechanics and enhance their subjective initiative and innovative ability.
