DBGT10K 2020-02 Port Opera Arc

Barrier work overlooking a port with the function of protecting the coast from the waves of the waters. Entities that constitute forms of control, retention and access in the exchange of land-water communications are defined in this class. They belong to the harbour works of landing like piers, docks, and the works of defense of the coasts such as brushes, dams etc. are merged into a single class because they identify entities that also perform multiple functions (moil with the function of barrier breakwaters¿).本类别所定义的实体，为在水陆交通往来中承担管控、滞留与通行管理功能的设施，其中包含俯瞰港口的护岸屏障工程——该类工程的核心功能为抵御水域波浪以保护海岸。本类别将靠岸港工设施（如突堤码头（pier）、船坞（dock））与海岸防护工事（如护岸、堤坝（dam）等）整合为单一分类，原因在于此类实体均具备多重功能，例如兼具屏障防波功能的moil。
