| 摘 要： | 海滩是激浪作用下泥沙在激浪带的堆积,是海岸带最活跃的地貌单元。近年来,由于世纪性的海平面上升,侵蚀型海滩范围扩大,侵蚀加重,海滩宽度变窄、坡度变陡和滩面物质粗化等问题日益严重,引起了广泛关注,亦成为海岸工程研究的热点课题之一。几十年的工程实践表明,海滩喂养与人工海滩是当前防护海滩侵蚀最有效的措施,并已为欧、美、日等国广泛应用。利用海岸地貌学原理方法,借鉴模拟环境条件类似的周边自然海滩的形成和演变规律,合理的设计海滩物质的颗粒大小和组成,海滩的坡度、高度、宽度以及填砂范围等关键参数,能够有效地使人工海滩更快的达到平衡状态并维持其稳定。在海滩的娱乐休闲功能在国际范围内日益受到重视的今天,这一方法在海岸工程应用上具有重要的现实意义。

| Abstract: | Beach is the most active geomorphologic part in the coastal zone,which is the depositional feature in the surf zone mainly controlled by the surf wave.Because of the sea level rise in the century,beach erosion is becoming more and more serious in the world during recent years.As the result,the width of the beach becomes narrow,the slope turns to be steep,and the compositional materials get to be coarse.From coastal engineering methods to deal with the problem of beach erosion during the past several decades,it has been proved that beach nourishment and artificial beach are the most effective and economic ways at the present stage and it has been profitable in many countries in America,Europe and Asia. Under the circumstance of the local geologic and geomorphologic setting,dynamic processes and sediment movement in different kinds of sandy beaches have been investigated,measured and modeled.With these kinds of natural physical models and according to several representative current foreign manuals for beach nourishment and artificial beach,an artificial beach has been designed to meet with the local requirement.Simulated with the US and Japanese empirical formulae,the designed borrow sand and beach slope would lead to a stable artificial beach with relatively less quantity of sand loss every year.This kind of practice is reasonable to be applied for in many places in China to protect the current beaches,and to meet with the needs of the development of the tourism. |
