Scope: In order to strengthen the maintenance, management, development and utilization of built civil air defense projects (especially early tunnels and tunnel projects), correctly assess the actual status of built civil air defense projects, prevent and reduce safety accidents in civil air defense projects, and promote the sound and rapid development of civil air defense construction, This standard is formulated in accordance with the relevant regulations of the national and provincial civil air defense offices. The construction forms of civil air defense projects are divided into tunnel projects, tunnel projects, single-construction excavation projects and air defense basements. Early tunnel projects mainly focused on identifying the safety of the structure and its impact on the external environment. Other projects mainly focused on identifying the safety of the structure and protection. The key points are evaluated and classified based on the appraisal results of the structure and protection, ventilation and chemical protection, water supply and drainage, and electrical disciplines.
