海上旅游人工岛防波堤方案设计

A Conceptual Design of Breakwaters for Offshore Artificial Tourism Island

海上人工岛建设在我国从无到有,逐渐发展,而防波堤是海上人工岛的重要组成部分,是海上人工岛抵御潮汐、波浪作用的安全屏障。但由于海上人工岛布置在离岸海域,缺乏陆域依托条件和掩护条件,海上人工岛防波堤建设条件往往比近岸更为恶劣,建设难度更大,同时对于旅游人工岛还需要考虑与陆上开发设施在平面布置、竖向布置、景观方面的结合和协调等因素。通过对秦皇岛某海上旅游人工岛防波堤的堤身材料、防浪标准、断面形式、景观协调等方面经验进行了总结,以期为同类工程所借鉴。

In China, the development of offshore artificial islands has been growing gradually out of nothing. Breakwaters are important components to offshore artificial island development and service as a safety barrier protecting the island against the action of tides and waves. However, offshore artificial islands are normally located in the open sea waters where are short of supporting and shield conditions from shore, hence the associated breakwaters are often more harsh and difficult to be constructed and built. At the meantime, the development of man-made tourism island also needs to consider the factors of combination and coordination with land development facilities in terms of plane layout, site leveling, landscape design, etc. This paper is expected to provide practical reference for similar projects by making a summary study of the materials, over-topping criteria, sections, landscape and other aspects adopted in the breakwater construction for an offshore artificial tourism island project in Qinhuangdao, China.
