| 摘 要： | 针对斜坡堤人工护面块体发生的接触碰撞问题，应用有限元离散元耦合法（FEMDEM）探讨了护面块体的碰撞应力、裂缝形成以及断裂过程。算例结果表明：断裂破坏通常发生在边界转角及角点，FEMDEM能有效地模拟连续介质向非连续介质的转化过程。

| Abstract: | According to the contact impact happening among the armor blocks of rubble mound breakwater,we probe into the collision stress, crack formation and fracturing process of armor blocks with the FEMDEM. It isfound that the fracture and failure generally occur in the outer edges corner or angular point, and FEMDEM is aneffective method for simulating the transition from continuous medium to the noncontinuous medium. |
