1.0.4 In the tunnel survey and design, national policies and regulations must be complied with, and the influence of tunnel project on ecology and water resources shall be emphasized. In tunnel construction, optimal land utilization, energy conservation and irrigation protection shall be considered, and noise, spoil and drain shall be treated properly.
1.0.5 Based on reliable complete data, operation and construction conditions shall be compromised in tunnel design according to terrain, geologic and ecological characteristic. The adopted plans, design principle and building structure of tunnel design shall meet the requirements of safety and usability, economic feasibility and environmental protection through technical and economic comparison / analyses.
1.0.6 Inner contour of newly-built railway tunnel must meet the requirements of current national standard "Structure Gauge for Standard Gauge Railways" (GB 146.2), and prospective rail type upgrade. As for newly-built railway tunnel for passenger train with running velocity 160 km/h, the inner contour shall be identified according to such factors as engine type, carriage sealability and passenger comfort. For single line tunnel, the cross-sectional area of clearance above the tunnel rail level shall not be less than 42m2; for double-line tunnel, shall not be less than 72m2; curve widening shall be considered additionally for curved tunnel. The section of tunnel arranged with rescue paths shall be increased according to the dimension of rescue paths, and the width of rescue path shall not be less than 1.25m.
The structural approach limit of tunnel for double-layered containerized traffic shall meet the relative regulations of the Ministry of Railways.
The inside contour of tunnel within the station shall meet the requirements of station yard design.
1.0.7 In renovation of existing line and second line extension, new railway standard shall adopted for newly-built tunnel, and should be adopted for renovated tunnel.
1.0.8 Tunnel structure shall meet the permanent structural design of 100-year normal service, and built tunnels shall meet the operating demand, facilitate maintenance work and be arranged with necessary facilities like safety protection.
1.0.9 Tunnel structure, water-proof / drainage design and constructional material shall be adopted in consideration of the influence on local environment.
1.0.10 In the tunnel design, relative national technical economic policies shall be implemented, and new theory, technology, material, equipment and process shall be adopted positively.
1.0.11 Applicable construction scheme shall be selected in tunnel design in accordance with engineering geology, hydrogeological conditions, combining with factors such as section size, lining type, tunnel length and construction period requirement.
1.0.12 For the designs of long tunnel, super long tunnel and tunnel with complicated geologic condition, the preparations for construction shall be established. As for tunnel suffered with gas or higher gas, implementation preparations for construction shall be established to prevent higher coal gas, coal exploring, coal revealing and coal pasting in accordance with this code and relative standards.
1.0.13 Means of construction transportation shall be adopted in tunnel design, based on ventilation and hole-inside hygiene standard.
1.0.14 Besides this code, the railway tunnel design shall comply with provisions of relative current compulsory standards.
