Perform design based on reliable geological data. 1.0.5 The subgrade engineering design should avoid high filling, deep excavation, long cutting; avoid areas with adverse geological conditions. In the comparison and selection of subgrade, bridge, tunnel engineering, it shall make comprehensive analysis in terms of technical conditions, construction conditions, land occupation, possible environmental and social impacts, urban construction planning, construction investment, operation and maintenance costs, to determine the type of project. 1.0.6 The railway train’s load shall be determined according to railway transportation characteristics, mobile equipment, design speed, etc. High- speed railway should adopt ZK load diagram. Intercity railway should adopt ZC load diagram. Passenger-freight railways should adopt ZKH load diagram. Heavy-load railway should use ZH load diagram. When the characteristics of passenger-freight railway meet the standards of heavy-duty railways, it shall use the ZH load diagram. 1.0.7 The design of subgrade engineering shall be based on railway grade, subgrade structure, and other factors; according to local conditions, reasonably select engineering materials. Meanwhile it shall meet the application conditions and use requirements of subgrade engineering. Subgrade fillers shall be surveyed and designed as engineering materials, to reasonably determine the earthwork allocation plan. 1.0.8 Subgrade engineering’s design shall consider the transition between subgrade and bridges, lateral structures, tunnels, and other subgrades of different structures. 1.0.9 The foundation treatment measures for the subgrade project shall be determined according to the railway grade, geological conditions, environmental requirements, embankment height, filler, construction period, etc. Meanwhile it shall meet the requirements of the stability of the subgrade and post-construction settlement. 1.0.10 The subgrade’s retaining structure shall be designed according to the geological conditions, track loads, train loads, whilst considering the effects of natural factors such as atmospheric precipitation, groundwater, surrounding environment. 1.0.11 The subgrade project shall have complete, systematic and unobstructed drainage facilities, which shall be reasonably connected with railway bridges and culverts, tunnels, stations and local drainage systems. 1.0.12 The structure of the catenary support foundation, sound barrier foundation, cable trough, cross-rail pipeline, comprehensive grounding provided on the roadbed shall be designed synchronously and constructed in a coordinated manner with the subgrade engineering, to ensure the integrity and stability of the subgrade. 1.0.13 Subgrade engineering shall promote the use of safe and reliable new technologies, new structures, new materials, new processes. 1.0.14 The land used for subgrade shall comply with the national construction land policy and relevant regulations, implement the principle of land conservation; meet the requirements of stability of subgrade, drainage facilities and protection fences. 1.0.15 In addition to this code, the design of railway subgrades shall also comply with the relevant national standards.
