1.0.1 This code is formulated with view to realizing safety and reliability, reasonable function, economy, energy conservation and environmental protection as well as advanced technology of metro design.
1.0.2 This code is applicable to the design of new steel wheel rail metro with the maximum running speed not exceeding 100km/h and driven by common motor.
1.0.3 The metro shall be arranged in main passenger transport channels with large passenger capacity in the city.
1.0.4 Metro design shall meet the comprehensive urban planning, urban rail transit network planning and short-term construction planning approved by governmental authorities, and shall be coordinated with comprehensive urban traffic planning.
1.0.5 The metro design, where relevant with line functional orientation, service level, system transport capacity, line route and starting and ending point, vehicle base site selection, resource sharing and etc., shall be determined according to the long-term network planning, and shall conform to the documents approved by governmental authorities.
1.0.6 For metro design, its relationship with other lines shall be handled according to long-term network planning, and connection conditions for subsequent project shall be reserved. The connection between metro lines and between metro and other traffic system shall realize transfer safety and convenience.
1.0.7 For metro design, scientific & technological innovation shall be advocated, and the resource saving and intensified construction principle shall be implemented.
1.0.8 The designed lifetime of metro projects shall be classified into initial term, short term and long term. Initial term may be determined as the 3rd year after the completion and opening to traffic; short term shall be determined as the 10th year after the completion and opening to traffic; long term shall be determined as the 25th year after the completion and opening to traffic.
1.0.9 The construction sequence and design length of each metro line shall be determined according to city morphology, scale, passenger flow distribution status, development demand and technical and economic reasonability principle, and shall be approved by chief drafting authority.
1.0.10 The vehicle base, parking lot, connecting line, operation control center and main substation shall be uniformly arranged according to network planning and construction sequence.
1.0.11 The construction scale, equipment capability of metro project and land areas of vehicle base and parking lot shall be determined according to the predicted long-term or passenger flow volume or that in passenger flow control period, train trafficability and resource sharing principle. The project which may be constructed by stages or equipment which may be arranged by stages should be subsequently constructed and arranged by stages.
1.0.12 For the main structure work of metro or other structural work greatly impacting the metro operation safety due to structural damage or general overhaul, its designed lifetime shall not be less than 100 years.
1.0.13 1435mm standard rail space shall be adopted for metro line, and right-traveling double-track line shall be adopted for main line.
1.0.14 Metro line shall be fully-enclosed and under high-density operation. The long-term maximum capacity in system design shall meet the requirements that the traveling density is not less than 30 pairs/h.
1.0.15 Upon determining the transport capacity of metro system, the standing passenger standard in effective unoccupied floor area in compartment should be calculated as 5~6 passengers/m2.
1.0.16 The metro vehicle base may be arranged for a line or for several lines according to specific conditions. Where the length of a line exceeds 20km, parking lot may be arranged in proper position according to operation requirements.
1.0.17 Upon designing shallowly-embedded, elevated and ground metro line, measures reducing noise, vibration and impact on ecological environment shall be taken.
1.0.18 Where conditions permit in areas beyond urban center, elevated or ground line should be adopted for metro; the type and size of elevated and ground building structure shall be coordinated with urban landscape and surrounding environment.
1.0.19 Measures resistant to fire, flood, earthquake, windstorm, ice and snow, lightning stroke and etc. shall be taken for metro design.
1.0.20 Safety protection facilities shall be arranged for metro. In addition to those specified in this code, the design of safety protection facilities shall also be reasonably equipped with interface, monitoring system, hazardous article treatment facilities and relevant room, etc.
1.0.21 Barrier-free traveling and using facilities shall be arranged for metro.
1.0.22 As for the underground metro tunnel passing through water areas like river and lake, where the underwater tunnel is damaged and water may jeopardize the safety of other sections on both ends, such ends shall be equipped with flood gate or other anti-flood measures shall be taken.
1.0.23 Mature products meeting the functional requirements and equipped with technical and economic reasonability shall be adopted for metro electromechanical equipment and vehicle; such equipment and vehicle shall also be standardized, serialized, based on domestic production as well as conducive to travel management, passenger transport organization and equipment maintenance.
1.0.24 Measures reducing construction cost and conducive to operation cost saving shall be taken for metro design provided that the safety, reliability and use function of metro are not affected.
1.0.25 Metro design shall not only meet the requirements stipulated in this code, but also comply with those in the current relevant ones of the nation.
