| 摘 要： | 航道疏浚产生的高浓度悬浮泥沙,对海域环境的影响不能忽视,建立二维悬浮物运输数学模型,模型考虑了不同潮流作用下悬浮物的运输。采用盘锦港海港区海流现场的观测数据对水动力模型进行验证,模拟值与实测值吻合较好。以盘锦港航道工程为例,预测疏浚作业在最不利情况下,悬浮泥沙对海水水质、环境敏感区的影响程度和范围,为环境影响评价提供科学依据。

| Abstract: | A 2-D math transport model of suspended particulate matters is established,in which the transport of suspended particulate matters in different tide actions are taken into account.The field synchronous monitoring data of Panjing harbor is used to validate the hydrodynamic model and it is indicated that the simulated Values agree with measured ones.Also,taking the waterway project of Panjing harbor as an example,the impact of SPM on sea water quality and marine creatures in the most unfavorable condition of ... |
