\nT/GBAS 93-2024 Bridge-Island-Tunnel Intelligent Operation and Maintenance Data. Immersion Tunnel Evaluation

Scope

Scope: This document specifies the basic requirements, evaluation methods, and classification for the evaluation of immersed tube tunnels, as well as the requirements for technical condition evaluation, adaptability evaluation, and evaluation metadata. This document is applicable to the technical condition evaluation and adaptability evaluation of highway immersed tube tunnels, and can be used as a reference for the evaluation of other types of tunnels. Main technical content: This document specifies the basic requirements, evaluation methods, and classification for the evaluation of immersed tube tunnels, as well as the requirements for technical condition evaluation, adaptability evaluation, and evaluation metadata. This document includes nine chapters: scope, normative references, terms and definitions, basic requirements, evaluation methods and classification, technical condition evaluation, adaptability evaluation, evaluation metadata, and appendices, covering the technical standards and data standards for the evaluation of immersed tube tunnels. In terms of technology, it specifies the evaluation methods and classification for immersed tube tunnels, proposes indicators and standards for the evaluation of the technical condition of civil structures, traffic engineering, and ancillary facilities, and specifies methods and standard indicators for the adaptability evaluation of structures or facilities such as joint relative deformation, ventilation facilities, and lighting facilities. In terms of data, it combines the technical process and data characteristics of the evaluation of immersed tube tunnels, and proposes methods for organizing and expressing metadata for the evaluation tasks, evaluation rules, evaluation weights, evaluation results, and evaluation reports of immersed tube tunnels.
