1.0.5 Design period of subway engineering shall be divided into three stages, such as preliminary stage, short-term stage and long-term stage. The preliminary stage of subway engineering shall be completed for train operation within 3 years, and short-term stage shall be within 10 years and long-term stage shall be within 25 years.
1.0.6 Construction scale and equipment capacity of subway engineering as well as area of land occupied by depot and stabling yard shall be determined according to forecasted long-term passenger flow volume and passing capacity of train. Design of engineering and configuration that can be constructed by stages shall consider by-stage extension and setting.
1.0.7 Design service life of main subway structure shall be 100 years.
1.0.8 Subway line shall adopt right driving and double line mode, and 1435mm standard gauge shall be adopted.
1.0.9 Subway line must adopt fully-close mode, and operation is high-density and depot-grouping operations are recommended to be adopted. The maximum operation capacity of long-term design is recommended to adopt 40 pairs of train per hour, but shall not be less than 30 pairs of train.
1.0.10 Train number of each group in preliminary, short-term and long-term stages shall be determined according to forecasted passenger flow volume, allowable passenger number of train and designed density of train flow separately.
Allowable passenger number of train shall be the total number of seat number on train and number of passengers who stand in train. Allowable passenger number at free area in train shall be 6/m2.
1.0.11 Subway depot shall be designed according to line network planning. According to concrete conditions, one depot can be set on each line or one depot can be shared by several lines.
Where length of one line exceeds 20km, extra stabling yard can be set at appropriate places according to operation requirements.
1.0.12 Convenient travel change shall be adopted at crosses among subway lines and other rail transit lines.
Travel change between subway lines and other general ground traffic lines is recommended to consider uniform planning.
1.0.13 During the design of shallowly-embedded and overhead ground lines, proper measures shall be adopted to reduce noise and vibration and to avoid influence on biological environment, and shall comply with emission provisions of applicable national standards.
The emission, sewage and solid waste discharged from the subway system shall meet the relevant discharge standards of the nation.
1.0.14 Determination of modes and quantity of ground and overhead subway devices shall consider influences on urban landscape and coordination with ambient environments.
1.0.15 Earthquake protection intensity shall be determined according to earthquake safety evaluation approved by competent authorities of local government.
1.0.16 Ground and overhead subway engineering crossing and adjacent to rivers shall be designed according to 1/100 flood frequency standard.
Subway engineering crossing rivers and lakes shall have flood-proof gate or adopt other flood-proof measures at appropriate positions at ends of relevant water area.
1.0.17 Subway design shall gradually realize electromechanical equipment integrated automation centralized on train travel direction and train operation.
1.0.18 Selection of subway electromechanical equipments and trains shall consider standardization and series, and China-made equipments are recommended to be adopted.
1.0.19 During subway design, measures shall be adopted to reduce engineering cost and operation cost, but subway safety, reliability and adaptability shall not be affected.
1.0.20 In addition to provisions prescribed herein, subway design shall also comply with relevant provisions of applicable national compulsive standards.
