综合国内外海岸演化数值研究进展,根据建模的目的和方法,砂质海岸数值模拟可以分为两大类,即岸线二维模型和海底冲淤三维模型。８０年代的发展趋势是将物理模型和数值模拟两种方法有机结合起来,９０年代开始出现数值模拟与卫星遥感技术结合的研究方法。粉砂淤泥质海岸的数值研究目前大致分为两种方法,即数学模型和泥沙模型。非线性科学在此领域日益得到重视 相似文献

从海岸演变、沉积过程、动力条件、泥沙运移等多角度阐述了北戴河海滩养护区域自然环境条件.北戴河海岸属于岬湾沙质海岸,具备岬湾养滩的天然条件,发育多条断续分布的水下沙坝,原滩剖面为侵蚀性剖面;西海滩蚀退速率＞2 m/a,属于严重侵蚀岸段;波浪的强浪向NNE和ENE,常浪向S,潮流为NE —SW向的往复流,沿岸泥沙净输沙方向为NE— SW向.洋河浅海泥沙中值粒径为0.31～0.58 mm,物化性质均符合养滩需求,为理想沙源.通过构建合适的人工岬头和离岸潜堤配合人工养滩可以恢复受蚀的海滩. 相似文献

以北戴河海滩横断面地形为例,采用平面二维水动力学、波浪、泥沙输运模型的数值计算方法,对不同沙坝位置进行了3种水位的极限波高入射数值试验,获取了坝内外波浪透射系数及稳定后的断面地形,并对波浪的消减及岸滩防护效果进行了分析与对比。结果表明:人工沙坝具有较好的消波效能,并能对岸滩起到较好的养护效果,将为类似侵蚀性海滩的生态修复提供科学依据。 相似文献

我们辽宁考察小组于1987年9月赴丹麦、荷兰进行海岸带开发技术考察。这次考察重点是:海岸工程、河口三角洲工程及开发利用,围海造田技术等方面。一、海岸工程海岸工程主要有港口建设工程和侵蚀海岸的防护工程。先谈港口建设,这两个国家,针对在泥沙来源丰富岸段、受大浪冲击岸段和在入海处建深水港的技术问题,首先是做好原型观测(即环境条件调查及评价),接着是做水工模拟试验,即物理模型。近年来,又普遍开展数学模型,并使二者结合。根据模 相似文献
