摘要
为了全面地了解珠海港LNG航道附近海域的潮流分布特征,在查阅有关该海域及其附近海域水文特征的基础上,结合模拟区附近的测流站、验潮站资料以及有关前期工作资料,采用数值模拟方法对工程海区及其附近海域的潮流场状况进行了数值模拟计算,再现了模拟区的潮流运动过程和特征。在海域潮流场进行模拟计算的基础上,对挖泥施工过程产生的悬浮物的扩散浓度场进行预测,以此来分析建设施工期间对附近海域水质的影响。
This paper focuses on the quantitative analysis and prediction on the impact of suspended sediment to the inshore water quality during Zhuhai port LNG channel dredging and construction process. To fully understand the distribution of inshore tidal current, on the basis of the inspection on the hydrological characteristics of the project sea area and its nearby waters, combining with the data from the test flow and tide gauge stations, as well as information on the preliminary work, this paper uses a numerical simulation method to simulate and calculates the state of tidal current field of the project sea area and its nearby waters, and reproduces its movement and characteristics. On the basis of the simulation of tidal current field, this model will predict the transport and diffusion of the suspension and be used to analyze the impact to the inshore water quality during construction.
