Scope

Scope: This document specifies the basic requirements for the hierarchical division and attributes of immersed tube tunnels, provides the metadata of immersed tube tunnels and their components, sub-components, and parts, and provides the classification and coding of immersed tube tunnel structures. This document is applicable to the standardization of immersed tube tunnel structures, including civil structures and auxiliary structures and facilities. Main technical content: This document specifies the basic requirements for the hierarchical division and attributes of immersed tube tunnels, provides the metadata of immersed tube tunnels and their components, sub-components, and parts, and provides the classification and coding of immersed tube tunnel structures. The main body of this document includes eight parts: scope, normative references, terms and definitions, basic requirements, immersed tube tunnel metadata, component metadata, sub-component metadata, and part metadata. This document classifies the hierarchical structure of immersed tube tunnels according to their spatial composition, construction process, stress characteristics, and fine maintenance, and determines the division principles and structural extensibility. It extracts the attributes of various structural levels of immersed tube tunnels according to business needs and classifies them according to attribute characteristics and attribute value sources. It constructs an immersed tube tunnel structure metadata model, uses the "parent object code" data element in the structure object metadata to link to the upper-level structure, and uses the same metadata to organize and describe the information of such common components in a unified manner. It also provides the rules and coding tables for the classification and coding of various hierarchical structures of immersed tube tunnels.
