【摘要】 为了更好地研究裂纹起裂的过程、裂纹扩展方向和速度的影响因素,研究裂纹的条件改变对岩体力学性质的影响,利用RFPA^2D软件建立相应的模型,改变参数将模拟结果与实验进行对比,研究了裂纹的倾角、裂纹的长度和均质性对单裂纹岩体强度的影响。更多还原

【Abstract】 In order to study influence factors of the process of crack crack, crack propagation direction and speed,research on the mechanical properties of rock mass crack conditions change,the mathematical model is set up by using RFPA^2D software,change the parameters to the simulation results compared with the experiment,studies the crack angle and crack length and uniformity of single crack rock mass strength.更多还原
