| 摘 要： | 在对天津港海域水文泥沙特征和冲淤演变进行分析的基础上,采用二维波浪潮流和泥沙数学模型对天津浮式LNG码头建设的水动力和泥沙问题进行研究,对取排水实施前后流场变化、防波堤建设对码头前流场影响进行了计算分析,同时预报了港池、航道正常年淤强以及一场大风期间淤积厚度,并通过资料分析得到泄洪排涝对工程区泥沙淤积不会产生明显的影响的结论。

| Abstract: | Based on the analysis of the hydrodynamic sediment conditions and seabed evolution in Tianjin port sea area,we use the mathematical models of wave,tidal current and sediment to study hydrodynamics and sediment problems of floating LNG terminal project.The change of tidal current field before and after the water intake and the influences of the construction of the breakwater on the flow field in front of the wharf are simulated and analyzed.At the same time,the deposition thickness in the harbor and waterway during normal years and a strong wind is given.Based on the data analysis,we can draw the conclusion that flood-releasing and waterlog-draining have no obvious effects on the sedimentation in the project area. |
