Champ d’application

This standard applies to the design, construction, or renovation of sites selected as emergency shelters for earthquake disasters through urban and rural planning. It covers the classification, site selection, and facility configuration of these shelters. It is mandatory for all designated earthquake shelter projects in China. The standard references GB 5749-2006 for drinking water quality and JGJ 50-2001 for barrier-free design.

Exigences techniques

The standard classifies earthquake emergency shelters into three categories based on facility configuration and duration of use: Class I (comprehensive facilities, >30 days), Class II (general facilities, 10-30 days), and Class III (basic facilities, <10 days). Designers must select the appropriate class based on the expected sheltering duration. For site selection, the standard mandates that locations must avoid earthquake fault zones, flood-prone areas, and regions near hazardous materials or high-voltage lines. Safety requirements dictate that sites should be flat, well-drained, and outside the collapse range of high-rise buildings. Indoor public venues must meet local seismic fortification requirements and undergo safety assessment per GB 18208.2-2001. Facility configuration requirements are tiered into basic facilities, general facilities, and comprehensive facilities. Basic facilities include emergency tents, medical aid stations, water supply, power supply, and sanitation systems. General facilities add fire-fighting equipment and emergency material reserves, while comprehensive facilities include helipads and parking lots. Specific clauses regarding site selection and basic facility setup are mandatory. Additional requirements cover seismic performance, mandating that all structures within the shelter must meet the seismic fortification requirements specified in GB 18306-2001. The standard also specifies zoning for tent areas, with each partition not exceeding 1000㎡, and requires barrier-free access in accordance with relevant codes.

Méthodes d’essai

This standard primarily focuses on design and construction criteria rather than specific laboratory testing methods. However, it mandates on-site safety assessments for buildings post-earthquake according to GB 18208.2-2001 and requires compliance verification for drinking water quality against GB 5749-2006. Evaluation procedures include checking the accessibility of evacuation routes and verifying the structural seismic performance.
