Scope

1.0.1 This Code is formulated to unify the technical standards for the design of
special railway earth structure, and to make the design of earth structure of
special area meet the requirements of safe application, advanced technology,
and reasonable economy.
1.0.2 This Code is applicable to the design of earth structure of special area for
high-speed railways, inter-city railways, mixed passenger and freight Class I
and Class II railways, and heavy-haul railways.
1.0.3 Projects of earth structure of special area shall strengthen geological
survey work; adopt comprehensive exploration and comprehensive analysis
methods, to identify the causes, scale, and engineering nature of unfavorable
geology and special rock and soil area, and to obtain reliable engineering
geological, hydrogeological, and environmental conditions data.
1.0.4 Projects of earth structure of special area shall fully consider the influence
of geological, climatic, and environmental factors; follow the principle of
prevention first and prevention and control combined; choose to pass at a
location with less hazard and easy to handle; and, should avoid high filling,
deep excavation, and long cutting, to reduce engineering risks.
1.0.5 Projects of earth structure of special area shall be designed according to
geotechnical structures. The physical and mechanical parameters required for
the design shall be determined by comprehensive analysis using data such as
in-situ test and indoor test, combined with the effects of natural factors such as
atmospheric precipitation, groundwater.
1.0.6 The design of projects of earth structure of special area shall be adapted
to local conditions; take reliable and effective reinforcing treatment measures,
to improve the ability to defend against natural disasters. When there are
various special rocks and soils or special conditions, comprehensive analysis
and comprehensive treatment shall be carried out. When conditions permit, it
is advisable to actively promote the application of new technologies, new
structures, new materials, and new processes.
1.0.7 For the design of filler for projects of earth structure of special area,
technical and economic comparisons shall be made for the schemes such as
cut-to-fill, collectively taking (abandoning) soil, and filler improvement. When
special rock and soil are used as a filler for improvement, through indoor and
outdoor tests, it shall propose relevant technical parameters and construction
technologies.
1.0.8 The design of side slope treatment for projects of earth structure of special
area shall pay attention to environmental protection, soil and water
conservation; and, take into account the requirements of saving land and
preservation of cultural relics; reduce damage to natural vegetation and
mountains; strengthen side slope retaining reinforcement and protection
measures; prevent induced geological disasters. When conditions permit,
green protection shall be adopted for the side slope.
1.0.9 The design of foundation treatment for projects of earth structure of
special area shall fully consider the factors such as topographic features,
foundation soil characteristics, hydrological conditions, foundation treatment
objectives, regional experience, particularities and sensitivities of the
surrounding environment, etc.; when necessary, combined with on-site tests
and testing, shall comprehensively determine appropriate foundation treatment
measures, construction methods, etc., to ensure the foundation treatment effect
and the surrounding environment safety.
