Scope

Main technical content: In recent years, the pace of urbanization in China has been accelerating, and urban rail transit construction has developed rapidly. Traditional construction methods include open (covered) excavation, shallow buried excavation, and hole-pile methods. On this basis, Chinese scholars and engineering technicians have developed the arch-cover method and successfully applied it in many cities. However, the arch-cover method still lacks unified standards or norms. The project of "Technical Specifications for the Arch-Cover Method in Urban Rail Transit Engineering" was initiated from this need, providing detailed regulations for the survey, design, and construction of the arch-cover method, and proposing the construction methods and structural forms of the arch-cover. This can effectively reduce project risks, reduce construction difficulties, and improve construction efficiency, with good economic and social benefits.
