摘要
以西藏日喀则市卡龙沟泄洪渠为例 ,应用固液两相流理论 ,探讨了三维瞬态ASM模型在渠道泥沙淤积计算中的应用。ASM模型可以完全考虑渠道在三维空间上的变化以及水沙之间的相互作用 ,通过模拟计算得到泥沙淤积过程及淤积量。结果表明 ,ASM模型可以用于河道泥沙计算 ,为河流整治及工程设计提供科学依据。
Taking the Kalong channel in Rikaze of Tibet as an example, the paper employed solid liquid two phase theory and explored the application of 3 D water sand ASM model in the calculation of sand deposition. The ASM model can give full consideration to the three dimensional variation in space and the interaction between water and sand.It shows that the ASM model can be used in the calculation of sand deposition and provide scientific basis for river regulation and project design through the simulation of the process and amount of deposition.
