| 摘 要： | 溜砂灾害是在山区中较常见的一种自然灾害,由于其爆发频繁、随机性强,常对交通运输、工农业生产和人民生命财产都带来极大的危害和损失。运用Mohr-Coulomb准则和能量守恒定律分别推导单个砂粒滑动判别条件和滚动条件;引入弹性恢复系数法描述砂粒间碰撞问题。该成果对于正确认识溜砂灾害形成机理有较为积极的作用,并且可以为溜砂灾害的防治提供参考。 |
| 关 键 词： | 溜砂坡 溜砂 计算模型 恢复系数 |

| Abstract: | As one of mountain hazards,sand-sliding hazard usually endangers severely transportation,industrial and agricultural production and our life and property because the frequency of their occurrences is high.Mohr-Coulomb criterion and energy conservation law were applied to deduce the sliding critical condition and rolling condition of single sand.The restitution coefficient was applied to describe the impact problem.The research findings may help to understand the formative mechanism of sand-sliding hazard and control of sand-sliding hazard. |
| Keywords: | sand-sliding slope sand-sliding motion models restitution coefficient |
