为评价泥沙运动对拟建绥中发电厂取水口的影响,进行了三维海岸动床模型试验。文章着重介绍模型的设计和验证。模型中采用天然海滩细沙作为模型沙。模型比尺采用先前在二维岸滩模型中的比尺公式确定,即λ_z=(λλ_x~(2/3)),式中λ_ω是泥沙的沉降速度比尺,λ_x和λ_x分别是垂直和水平几何比尺。在正式试验前进行了大量的验证试验,包括岸滩剖面、沿岸流、沿岸输沙率和冲淤时间比尺等。文章最后简要介绍了试验结果。
In order to evaluate the effect of sediment movement on the water intake of the proposed Suizhong Power Plant, a 3-D coast dynamic bed model test was conducted. The article focuses on the design and verification of the model. The model uses natural beach sand as model sand. The model scale is determined using the scale formula previously used in the two-dimensional beach model, λ_z = (λλ_x ~ (2/3)) where λ_ω is the sedimentation velocity scale of the sediment and λ_x and λ_x are vertical and Horizontal geometric scale. A large number of validation tests have been conducted prior to the official test, including shoreline profile, coastal flow, coastal sediment transport, and scouring and silting time scales. The article concludes with a brief introduction of the test results.
