【摘要】：为解决曹妃甸首钢围海造地工程用沙问题,计划在曹妃甸甸头东侧滩涂取沙,因关系到曹妃甸岸滩的稳定性,拟通过波浪泥沙物理模型进行试验研究,探讨取沙对岸滩向/离岸运动的影响。基于河口海岸物理模型相似理论,探讨了模型比尺的确定方法及模型沙的选取;在缺乏合适验证资料的情况下,通过三种途径对物理模型的合理性和可靠性进行验证试验,验证试验表明,本模型可将二维沙滩剖面特性研究成果应用于三维条件。
[Abstract]:In order to solve the problem of sand used in the reclamation project of Shougang, Caofeidian, it is planned to take sand from the beach on the east side of Caofeidian head. Because it is related to the stability of Caofeidian bank, it is proposed to carry out an experimental study by using the wave and sediment physical model. The effect of sand extraction on shoreline / offshore motion was discussed. Based on the similarity theory of physical models of estuaries and coasts, the determination method of model scale and the selection of model sand are discussed, and the rationality and reliability of physical models are verified by three ways in the absence of suitable verification data. The experimental results show that the model can be applied to 3D conditions.
