摘要
Abstract
Through the mathematic model of planar 2D tide and suspended sediment diffusion and movement,the process of suspended sedimenz diffusion and movement in some excavation project is simulated. Finiteelement method with non-structural mesh is applied for discrete solution. By combining with actual project, the continuous line source is adopted in the model to simulate the increment suspended sediment during excavation.The mechanism of suspended sediment diffusion and movement is summarized, which will provide scientific evidence for the environmental effect evaluation.关键词
