摘要

摘要:
启东碧海银沙沙滩位于长江入海口北支口北侧启东嘴附近，是典型的粉砂淤泥质海岸，受长江江流、海水风暴潮和潮流等影响，海岸地质背景较为复杂，以海陆交互作用的潮间带和水下三角洲地貌为主，本身地质条件并不适合作为沙滩旅游项目的开发。自2011年起，恒大集团在这里使用泥岸人造沙滩技术，通过围堤筑坝、滤沙净水，成功建成了围海7.23 km²、滩长3.5 km的恒大海上威尼斯碧海银沙项目。在该项目建设之前有上海金山城市沙滩、天津东疆浴场、潍坊央子人造沙滩等多个人造沙滩建成，其在上述人造沙滩成功案例的经验基础之上，结合自身地质条件，成功总结出了适合自身的一套围海成湖、吹沙净水、泥沙隔板及防泥网的工程技术系统，为中国粉砂淤泥质海岸人造沙滩建设提供了又一实践经验。

Abstract:
The Qidong City is located on the north side of the North Branch of the Yangtze River Estuary near the Qidongzui. It is a typical silty and muddy coast. Under the joint influence of the Yangtze River current, sea storm surge and tidal current, the geological background of the coast is rather complex. It is dominated by an intertidal zone and a related underwater delta resulted from the interaction of land and sea. Its geological conditions are in fact not favored to the development of beach tourism projects. Since the construction of the artificial sand beach on the mud bank started in 2011, the Evergrande Sea Venice Bihai Silver sand beach project has been successfully completed with a sea enclosure of 7.23 km², and a beach length of 3.5 km by damming and sand filtering. In fact, prior to the successful construction of the project, several man-made beaches had been built in China, such as the Jinshan City beach in Shanghai, the Dongjiang bathing beach in Tianjin, and the Yangzi man-made beach in Weifang. Based on the successful experiences in previous projects, combined with its geological conditions, we carefully summarized the Qidong case for a set of engineering and technical guidelines suitable for its own, such as making the sea a lake, blowing sand for water purification, construction of sediment barrier and mud prevention net and so on, which provide good references for similar projectsin other places.
