摘　　要：临海工程项目的防洪安全受洪水及海潮影响,为确定盘锦某精细化工及原料工程项目的风险源及防洪(潮)水位,需要综合分析现状及规划工况条件下辽河、大辽河及辽东湾海潮对工程项目的影响,并采用适当的洪水及潮流数学模型分别进行计算。经分析,确定采用MIKE FLOOD一二维耦合溃堤数学模型,分析大辽河洪水对工程项目的影响;采用MIKE21 FM二维潮流数学模型,分析辽东湾海潮对工程项目的影响。计算结果表明,现状工况条件下工程区主要风险源来自海潮,规划工况条件下工程区主要风险源来自大辽河洪水,工程建设需要综合考虑洪水及海潮的影响。文中采用的计算方法和结论可为类似工程项目的防洪(潮)水位确定及报告编制提供依据。The flood control safety of coastal engineering projects is affected by flood and sea tide.In order to determine the risk sources and flood(tide)control level of a fine chemical and raw material engineering project in Panjin city,it is necessary to comprehensively analyze the impact of the Liaohe River,Daliao River and Liaodong Bay sea tide on the engineering project under the current situation and the planning situation.Furthermore,we need to use appropriate flood and tidal current mathematical models to calculate it respectively.Based on the above analysis,MIKE FLOOD 1D-2D coupling mathematical model was adopted to analyze the impact of Daliao River flood on the project.MIKE21 FM 2D tidal current mathematical model was adopted to analyze the impact of Liaodong Bay tide on the project.As the calculation results indicated,under the current situation,the main risk source of the project was tide.And under the planning situation,the main risk source of the project was the flood from Daliao River.The impact of flood and tide was supposed to be studied comprehensively in the project.The calculation method and conclusions adopted in this paper have provided a basis for the determination of flood(tide)level of similar projects and the preparation of relevant reports.
