The scheme of the tunnel shall be determined after risk assessment and technical and economic comparison and analysis. The design of tunnels shall embody the design concept of being people-oriented, serving for the transportation, energy conservation and environment protection, being technically advanced, cost-effective, durable, and convenient for maintenance and repair. 1.0.4 The tunnel structure may be designed by plastic stage method and allowable stress method. When it is designed by ultimate state method, the provisions in relevant standards shall be complied with. 1 .0.5 According to the length, the tunnels may be classified into short tunnels (with the length being shorter than or equal to 500 m), medium-long tunnels (with the length ranging from 500 m to 3 000 m), long tunnels (with the length ranging from 3 000 m to 10 000 m) and extra-long tunnels (with the length being more than 10 000 m). Note. Tunnel length is the distance between tunnel portals, with the starting point and ending point being the intersection of the railway centreline and the intersecting line between the portal face and rail top surface. For double-track railway tunnels, the tunnel length shall be the length of the left track: for tunnels in a railway station, the tunnel length shall be the length of the main line；for tunnels with buffer structures, the tunnel length shall be calculated from the starting point of the buffer structure. 1.0.6 According to the excavation span, the tunnels may be classified into small-span tunnels (with the span ranging from 5 m to 8.5 m), medium-span tunnels (with the span ranging from 8.5 m to 12 m), large-span tunnels (with the span ranging from 12 m to 14 m) and extra-large-span tunnels (with the span being more than 14 m). Note. The excavation span of the tunnel cross-section of the tunnel. 1.0.7 In tunnel prospecting, importance shall be attached to the influence of the tunnel works on the ecological environment and the water resources. During tunnel construction, attention shall be paid to land saving, energy conservation and protection of farmland and water conservancy facilities. Noise control works at tunnel portals, muck disposal works, and drainage works etc. shall be designed permanent works. 1 .0.8 Tunnels shall be in stable ground. The selection of the tunnel portal locations shall follow the principle of “early entrance and late exit”.3 Overall Design3.1 General Requirements 3.1.1 In the survey and design of tunnels, the technical standard of the railway line, environment and other factors shall be disaster prevention and protection, operation and considered, and the location, structural type, construction method, construction period and project investment etc. of the tunnel shall be determined rationally, to ensure the safety, reliability and maintenance, rescue durability of the tunnel. 3.1.2 Tunnels should not run through zones with overly complex engineering geological conditions and hydrogeological conditions and seriously unfavourable geological with karst, such as zones underground rivers and goaf. 3.1.3 For extra-long double-track tunnels and double-track tunnels with complex geological conditions, technical and economic comparison, and contrast shall be made between the scheme of single double-track tube and the scheme of twin single-track tubes in accordance with the construction methods, construction organization, and the arrangement of the works for operation, disaster prevention, evacuation, and rescue etc. 3.1.4 In the design of tunnels located in urban areas, the influence of the construction and operation of the tunnel on the environment, as well as the influence of the city planning and the surrounding environment on the tunnel structure, shall be considered. 3.1.5 In the design of the lining cross-section of tunnels, rational structural shapes, and dimensions shall be determined in accordance with the geological conditions, construction methods, environment conditions and other factors. 3.1.6 In the construction plan of tunnels, rational progress rate and construction period shall be planned in accordance with the construction methods, construction ventilation, construction drainage, the mechanical equipment provided and the construction adits new construction risk control, as well as arranged. 3.1.7 In the design of the waterproofing and drainage of tunnels, enough attention shall be paid to the treatment of the surface water and groundwater. The drainage system of the tunnel shall be smooth and unblocked and shall meet the maintenance requirements. 3.1.8 The site conditions of the muck disposal area shall be investigated. The design of the muck shall comply with the water conservation and environment protection requirements. The disposal arrangement of the muck disposal sites shall not impact the safety of the nearby buildings (structures). 3.2 Selection of Tunnel Location 3.2.1 The plane locations of extra-long tunnels and tunnels with complex geological conditions shall of technical and economic comparison and contrast on the basis of large scope of be selected by geological investigations, considering the construction schemes, construction periods, related works and means operation conditions etc. 3.2.2 For railway line sections passing along rivers and by mountains, when the line passes the sections by means of tunnels, the route selection shall comply with the following requirements.1 The line should be moved to the mountain side so to avoid the adverse effect of the too thinrock mass on the outside of the tunnel, river scouring and unfavourable geological conditions on the stability of the tunnel.2 Comparison and contrast shall be made between the short tunnel group scheme and the longtunnel scheme. 3.2.3 For tunnels adjacent to attention shall be paid to the impact of the collapse of the reservoir banks and the scouring of the rivers etc. on the stability of the tunnels. 3.2.4 The selection of the tunnel route in karst region shall comply with the following provisions. 1 The result of the geological interpretations of the remote sensing images shall be fully utilized, the development of karst in the region shall be analysed and studied, and the tunnel shall be located preferably in where the karst and karst water have relatively little developed. 2 The tunnel shall be located at the high position as far as possible. The tunnel should not pass through seasonally alternating belts, horizontal runoff belts and deep slow flowing belts where karst water develops. 3 Tunnels passing by mountains should be located along the side where karst develops little, and the tunnels shall be located at positions higher than the karst water discharging belts. 4 Tunnels shall not pass through tectonic zones with seriously-developed karsts, negative relief, with developed underground rivers, areas with huge caves, karst group, as well and karst water discharge areas. 5 The tunnel shall pass, with large angle, the contact6 The tunnel shall be close to arid above the existing underground works or other undergroundto intercept and discharge the groundwater under the effect of the depression cone formed by other underground works. 7 The longitudinal slope of the route shall preferably be double-spur shape, and the gradient of the longitudinal slope in the tunnel should be increased appropriately. 8 When the route crosses the underground river, the tunnel shall be located above the roof of the the underground river with large angle, and adequate safety thickness as underground river and shall be ensured below the tunnel floor. 3.2.5 The selection of the tunnel route in regions with high ground temperature shall comply with the following: 1 The tunnel shall be in ground with relative low ground temperature. 2 When the route passes through regions with high ground temperature, the plane and longitudinal profile of the route shall be optimized so that the railway line can pass the region with high route location and short distance. 3 In valley region, the route should be located on the side close to the mountain and along the river, so as to reduce the length of the construction adits. 3.2.6 In very cold and code regions, the tunnel shall be located as far as possible in areas with low groundwater level, with relative low water content of surrounding rock and with relative small freezing-thawing effect on the surrounding rock. The tunnel portals should be located at places with little wind, but with good sunshine. 3.2.7 The tunnel shall not pass through the landslide zones, when it has to pass through the landslide zones, the tunnel body shall be located in the stable ground at certain depth below the slide surface, and reliable engineering measures shall be taken. 3.5.7 Risk management reports shall be submitted in each design stage.
