【摘要】：海岸帶是陸地與海洋的接觸地帶,也是全球生態(tài)環(huán)境的脆弱帶,易受風暴潮、海平面上升和人類活動的影響,常出現(xiàn)海岸線變遷、海岸侵蝕、港灣淤積等現(xiàn)象,也容易發(fā)生環(huán)境污染等一系列海岸帶環(huán)境問題。因此,從事海岸地貌的研究,了解海岸的演變過程與變化趨勢,掌握海岸防護技術方法,對港口建設、圍墾、旅游等自然資源的合理開發(fā)利用,都有著十分重要的意義。 我國的海岸整治措施以傳統(tǒng)硬工程措施、線防護為主。由于海岸綜合整治耗資巨大、技術難度高,目前僅在個別海域開展,尚缺乏全國性的海岸綜合整治方案。對于海岸侵蝕、港灣淤積等海域空間資源受損問題相關的整治理論與工程技術沒有較為系統(tǒng)的研究,更無規(guī)范性的整治規(guī)劃設計技術方法體系可供參考。 本文用控制體的概念解釋了海岸演變機制,調(diào)查了我國海岸類型及分布、海岸問題的特點、原因及研究背景。通過借鑒歐美等國家成熟的海岸工程手冊,并在對比各國海岸工程手冊規(guī)范和分析海岸成功整治案例的基礎上,總結(jié)了海堤、丁壩、離岸堤、人工沙灘、人工岬灣養(yǎng)灘綜合法等常用侵蝕防護工程措施以及防波堤、防沙導流堤等防沙防淤工程措施的特點、設計標準和技術規(guī)范,并給出它們的適用范圍,及建議的組合方式,以發(fā)揮綜合的海岸整治防護效果。 為了提高海岸帶的綜合利用價值,充分發(fā)揮其經(jīng)濟、社會、生態(tài)效益,海岸防護觀念從原來線的防護轉(zhuǎn)變?yōu)槊娴姆雷o,將海岸帶作為一個整體進行綜合整治和利用開發(fā)。結(jié)合國內(nèi)外成功的工程實例,總結(jié)歸納了海岸綜合整治和綜合開發(fā)的原則和方法。文中最后做了總結(jié)并指出本文的不足之處。
[Abstract]:Coastal zone is the contact zone between land and ocean, and it is also the fragile zone of global ecological environment. It is vulnerable to storm surges, sea level rise and human activities, and often occurs such phenomena as coastline changes, coastal erosion, estuary siltation and so on. Also prone to environmental pollution and a series of coastal environmental problems. Therefore, it is of great significance to study coastal landforms, to understand the evolution process and trend of the coast, to master the technical methods of coastal protection, and to develop and utilize the natural resources such as port construction, reclamation, tourism and so on. China's coastal regulation measures to traditional hard engineering measures, line protection. Because of the huge cost and high technical difficulty of coastal comprehensive regulation, it is only carried out in individual sea area at present, and there is still no national comprehensive coastal treatment plan. There is no systematic study on the regulation theory and engineering technology related to the damage of spatial resources in coastal erosion, harbor siltation and other sea areas, and there is no normative technical system of regulation planning and design for reference. In this paper, the mechanism of coastal evolution is explained by the concept of control body, and the types and distribution of coast in China, the characteristics, causes and research background of coastal problems are investigated. Based on the reference of mature coastal engineering manuals in Europe and America, and on the basis of comparing the specifications of coastal engineering manuals and analyzing the successful coastal regulation cases, the seawall, spur dike, offshore embankment, artificial sand beach are summarized. The characteristics, design standards and technical specifications of the commonly used erosion protection engineering measures, such as artificial headland beach maintenance comprehensive method, breakwater, sand diversion dike and so on, are given, and their applicable scope and suggested combination mode are given. In order to play a comprehensive coastal protection effect. In order to improve the comprehensive utilization value of the coastal zone and give full play to its economic, social and ecological benefits, the concept of coastal protection changed from the protection of the original line to the protection of the surface, and the coastal zone as a whole was comprehensively renovated and exploited. Combined with successful engineering examples at home and abroad, the principles and methods of comprehensive coastal regulation and development are summarized. At the end of the paper, the author summarizes and points out the deficiency of this paper.
