摘　　要：广东核电站位于大亚湾,防波堤口门处台风期设计波高H_(1/10)达6.7m,而泵房前进水口允许波高H_(1/3)仅0.3m。为此,在进水口前布置了东、西导堤加以掩护,形成二次绕射,以满足进水口的泊稳要求,同时,港内边界由全反射的重力式码头和部分反射的斜坡式防波堤、导堤及护岸等组成。所以,本文建立了具有任意反射率复杂边界的多港湾波浪绕射的数学模型。数值计算结果与相同条件下的物理模型试验结果吻合良好。The harbour of Guangdong Nuclear Plant is situated at Daya Bay. The design wave height(H 1/10 )at the entrance of the harbour is about 6.7m in typhoon period,and the permissible wave height (H 1/a ) in front of the pump station should be lessthan 0. 3m. Therefore, in order to meet this requirement the water intake should be further protected by tow jetties (the western and eastern jetties) to form an inner intake basin, in which the sub-diffraction waves are generated.Thus, in estimating the wave agitation in harbour basins,different kinds of boundaries with different reflection coefficients should be taken into consideration,including full reflection for gravity type quay and partial reflection for rubble mound breakwater,shore wall and jetties. A mathematical model for wave diffraction in a multi-basin area with arbitrary reflective boundaries is presented in this paper. The agreement between the results of mathematical model and the results obtained by the physical model is favourable.
