| 摘 要： | 港池疏浚产生的高浓度悬浮泥沙,对海域环境的影响不能忽视。在建立近海悬浮物二维输移扩散数值模型的基础上.采用有限元分步杂交方法求解,对两种不同施工方案下悬浮物的输移扩散进行预测模拟。根据预测结果,对比分析两种施工方法可能对附近海域水质环境适成影响的程度,为施工方案的选择提供科学依据。

| Abstract: | Suspended particulate matter(SPM)of high concentration caused by harbour dred- ging can bring impact on marine environment.In this paper a two dimensional model of transport and diffusion of SPM was established.On the basis,Split steps finite element method is used to simulate the transport and diffusion of dredged matter in two construction cases.According to the prediction result,the impact of SPM on the water environment were analyzed and balanced in two cases,scientific proof about construction schemes selecting is obtained. |

| Keywords: | dredging up suspended particulate matter transport and diffusion numerical model |
