| 摘 要： | 通过对甘肃省舟曲县城后山三眼峪沟特大泥石流灾害的现场调查,获取了舟曲三眼峪沟泥石流相关资料,据此分别对三眼峪沟及其支沟(大峪沟、小峪沟)泥石流动力学的泥石流流速、流量及冲击力进行分析与计算.计算结果表明:流速、流量达到特大泥石流的规模,冲击力远远大于该沟防护工程的设计.提出了三眼峪泥石流沟针对性防灾减灾建议. |
| 关 键 词： | 舟曲 三眼峪沟 泥石流 动力学参数 |

| Abstract: | By the site investigation of the debris flow disaster Sanyanyu gully,the first-hand data of the disaster was obtained.The mud-rock flow velocity,flow,impact of Sanyanyu gully(Dayu gully and Xiaoyu gully) were analyzed and calculated based on these collected data.The calculation results show that mud-rock flow velocity and flow reach the scale of super debris flow,and the impact is much greater than protection engineering design of the gully.At last,the specific suggestions on disaster prevention are given based on these studies. |
| Keywords: | Zhouqu Sanyanyu gully debris flow dynamics parameters |
