大型填海造地工程堵口方案设计

作为拓展生存空间和发展空间重要手段的填海造地在世界上众多沿海国家得到广泛实践。填海造地的主要工程内容是围堰和吹(回)填,而围堰的合龙设计对工程的施工、安全和工程造价影响巨大。以大型填海造地工程为例,论述如何根据工程地质、地形、潮流等特点,合理确定龙口的位置以及分区分仓、水力计算、龙口保护、施工安全和经济性等内容,并总结龙口设计的关键点和标准化流程。

Reclamation closure design of large-scale land formation project

As an important method to expand living and development space,land reclamation is widely practiced in many coastal countries in the world.The main engineering content of land reclamation includes the dyke and reclamation,and the closure design has great influences on the construction,safety and cost of the project.This paper uses a mega project as an example to discuss how to reasonably determine the closure position,dividing regions,hydraulic calculations,protecting closure,construction security,economical efficiency,etc.,and summarizes the key points and standardized process of the closure design.
