| 摘 要： | 在物源条件一定的情况下,通过实验模拟,研究水力类泥石流在不同流速、流量和纵比降组合条件下的沟道启动、揭底机理和运动特征。用Herschel-ulkley模型分析泥石流运动时的受力情况,整理实验数据获得侵蚀高度与纵比降的关系和流量与揭底距离的关系。

| Abstract: | With certain rock material,hydraulic debris flow was simulated to explore the gulch-start,bottom-scour and motion characteristics at different combinations of flow velocity,flow quantity and vertical gradient.And Herschel-Bulkley Model was used to analyze forces exerted as the debris flow moves.The experimental data treatment resulted in the relation of bottom-scour to flow quantity and that of erosion depth to vertical gradient. |
