摘要
海域冲淤演变是影响电厂取排水口安全运行的关键因素。基于工程所在海域水沙运动规律、地貌演变规律,采用二维潮流泥沙数学模型计算分析了某滨海电厂与码头一体建设的取排水口所在海域水动力条件变化和冲淤演变规律,研究结果表明:工程建设后,码头南北两侧水域流速减小,西南区域靠近潮汐水道主槽位置流速增大。受流速变化影响,码头南北两侧海域淤积增强,码头西南区域海域以冲刷为主,取水口位于码头港池内,工程后冲淤幅度为0.026 m/a,对取水口取水影响有限。研究结果可为码头和取水口工程布置提供理论依据和技术支撑。
The evolution of erosion and deposition in sea area is the key factor affecting the safe operation of power plant water intake-outlet.Based on the laws of water and sediment movement and geomorphic evolution in the sea area,a two-dimensional tidal and sediment mathematical model is used to calculate and analyze the changes of hydrodynamic conditions and the evolution law of erosion and deposition in the sea area,where the water intake-outlet of a coastal power plant and wharf is located.The research results show that:after the construction of the project,the velocity of the waters on the north and south sides of the wharf decreases,while the velocity on the southwest area near the main channel of the tidal waterway increases.Under the influence of velocity change,the sea area on the north and south sides of the wharf is enhanced,and the sea area in the southwest of the wharf is mainly scour.The water intake is located in the wharf basin,and the range of erosion and deposition after the project is 0.026 m/a,which has a limited impact on the water intake.The research results can provide theoretical basis and technical support for the layout of wharf and water intake scheme.
