摘要
建立了平面2D潮流和悬沙增量输移扩散的数学模型,通过有限单元法离散求解此模型,应用该模型对苍南电厂港池和航道疏浚过程中的悬沙扩散输移进行模拟,挖泥过程中的悬沙增量采用恒定源强,再现了疏浚过程中增量悬沙的输移扩散机理。
The planar 2D mathematical model on dispersion-transportation of tide and increased suspended sediment, which is solved with finite element method, is established and applied to simulate the dispersion- transportation of suspended sediment of Cangnan Power Plant during dredging engineering of the harbor basin and channel. The source intensity of increased suspended sediment during dredging adopts a constant value, and the result reveals the dispersion-transportation mechanism of the suspended sediment during dredging.
