| 摘 要： | 针对水库水流和泥沙淤积特点,将水库进行物理模型概化处理,修建长6 m,宽2 m,高0.5 m的概化物理模型;以其模型试验结果验证了采用Eulerian两相流模型、标准k-ε紊流模型及推移质冲淤计算模式,计算的水沙淤积形态,并将该数学模型应用于实际水库工程中,初步分析了水库库尾泥沙淤积形态与库岸坍塌破坏的相互作用关系。

| Abstract: | A conceptualized physical model was built, which is 6.0m long, 2.0m wide and 0.5m high to simulate a reservoir according to the flow and sediment deposit characteristics of the reservoir. The model test results verified the Eulerian two- phase flow model, the standard k - ε turbulent flow model, the bed load flushing calculation mode and the calculation of sediment deposit patterns. The mathematical model was applied to the reservoir projects to analyze the interaction relationship between the pattern of sediment deposit at the tail of a reservoir and the reservoir bank collapse. |
