碩士 === 逢甲大學 === 水利工程與資源保育研究所 === 96 === This study is for the existing sediment concentration of debris flow formula in practical and theoretical application. The results of the calculations may have some unreasonable results; therefore scholars use both theoretical and empirical analysis to establish sediment concentration of debris flow and riverbed soil collocation models. In accordance with test data of channel experiment and Regression Analysis from scholars in the past, some application problems of sediment concentration of debris flow formula of can be solved with above experiment and analysis. According to preliminary research, results can be summarized as following points: 1.The introduction of the concept of bed inertia shows the bed surface soil collocation affecting Sediment Concentration of Debris Flow. After theoretical analysis, Sediment Concentration of Debris Flow can be shown as: The bed inertia and the bed surface soil collocation are related, the test data after regression analysis can be formed to. 2.Dimensional analysis and application of previous test data, the study established the experience of Sediment Concentration of Debris Flow: In comparison with above formula and the existing Sediment Concentration of Debris Flow, the biggest difference is above formula proving the effect of bed surface soil and upstream aboard channel discharge.
