本文通过刚块动力模型试验，对具有光滑表面刚性块体的动、静摩擦系数关系进行了初步探讨，并以模型试验结果验证了离散元数值模型的正确性。离散元适宜用于岩质边坡的稳定分析，文中对离散元动力分析中有关参数的选择作了研究，得到了一些对工程计算与分析有参考价值的建议。
In this paper, through the rigid block dynamic model test, the relationship between the dynamic and static friction coefficient of a rigid block with a smooth surface is discussed. The correctness of the discrete element model is verified by model test results. Discrete element is suitable for the stability analysis of rock slopes. The selection of relevant parameters in the discrete element dynamic analysis is studied in this paper. Some suggestions for engineering calculation and analysis are obtained.
