摘　　要：滨海电厂取水口附近泥沙研究对电厂建成后安全运行是关键内容之一。对取水口影响最大的动力因素是潮流和波浪,我国华南沿海部分地区潮流动力相对较弱,波浪动力成为取水口底沙运动的主要动力。波浪泥沙对取水口的影响较为复杂,更关注取水口附近局部区域的泥沙运动,更适合通过物理模型试验方式研究该问题,因此,波浪泥沙物理模型试验成为滨海取水口设计的重要技术支撑。该文对华南某滨海电厂取水口布置开展物理模型试验,研究取水口附近的泥沙运动规律及泥沙骤淤情况,根据试验结果和实测数据,分析对比物理模型试验成果的合理性和可靠性,提出取水防沙工程方案,为工程设计提供试验依据,可为滨海工程取水口取水防沙的模型试验和布置设计提供借鉴。The research of sediment at water intake of power plants is one of the key contents for the safe operation of the power plant after completion.Tidal current and wave are the most influential dynamic factors on the water intake of coastal power plants.In some coastal areas of southeast China,the tidal power is relatively weak,and the wave power becomes the main driving force of the bottom sediment movement near the intake.Therefore,model tests of wave and sediment at the intake can be an important technical support for the design of the water intake of the power plant.In this paper,a physical model test was carried out and optimized water intake and sediment control project scheme was proposed according to the results.Based on the measured data,the rationality and reliability of the physical model were analyzed,which can provide references for physical model tests of wave and sediment at the intake of coastal constructions.
