    摘要: 本研究應用模型試驗及數值模擬分析潰壩時潰口流量與水位之關係,試驗之潰壩模型置於底床波降S0=0.001、長12.00m及寬0.775m而渠壁深0.70m之直線渠槽下游端。潰口形狀為矩形。壩體設置可分為三層,第一層為潰口形狀,第二層為一較潰口最大寬度寬之左右對稱雙開門板,第三層為一可向上抽離之隔板。並設定殘留壩高W=0.250m、W=0.166m、W=0.125m、W=0.100m和W=0.000m以模擬非完全潰壩之現象。
    本研究利用FLUENT商業軟體建立非恆態流之模式,以紊流模式依據三維模型進行潰壩模擬,其模擬條件與試驗條件相同,並將模擬結果與試驗結果比較分析。
    In this study use the model and simulation analysis of discharge-water stage relationship at dam-break site. The dam-break model to placed on straight channel downstream. The experiment was conducted in flume 12.00m long, 0.775m wide and 0.7m high with bed slope=0.001. Shape of dam-break is rectangular. Dam is divided into three levels, the first level is the shape of dam-break, the second level is the gate and the third level is the vertical sliding gate. The test set residual dam W=0.250m high, W=0.166m high, W=0.125m high, W=0.100m high and no residual dam.
    In this study use the FLUENT to establish the unsteady flow numerical model. Simulate the dam-break by turbulence model based on three-dimensional model. The simulation conditions and model conditions are the same. Comparative and analysis of simulation and experimental results.
