| 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: | Sand excavation will be conducted on the east of Caofeidian east intertidal zone for Shougang Group, related to the stability of Caofeidian shore. A hydraulic model experiment has been carried out on the sand movement under waves off the beach, and the impact of the sand excavation analyzed, especially, the offshore transport of sand. Three methods are used for reliability analysis. The use of sediment 2 D motion of beach for 3 D is creative. |
