摘要: |
依据三峡坝区模型中从水库开始连水到基本冲淤平衡阶段,对坝前冲刷漏斗的形成过程进行量测的资料分析,发现其经历了淤积—冲刷—基本平衡的过程。在对冲刷漏斗形成的分析基础上,提出了漏斗冲刷深度的计算式。 |

Abstract: |
Based on the data, which represent the variation of the scouring funnel from the storage to the balance of the reservoir in the physical model of Three Gorges,the results that the forming process of the scouring funnel is composed of silting,scouring and basic balance are obtained by this paper.The reasons caused the funnel variation are discussed.The formula that expresses the whole process of souring funnel is presented. |
