Development countermeasures for construction of underground space system of transportation

The rapid advancement of industrialization and urbanization has led to the increasingly prominent problems such as urban land scarcity and traffic congestion. For the development of underground space of transportation the development and utilization of underground, ground, and upground are considered through the overall planning to create a comprehensive hub and form a three-dimensional transportation, which has become an important solution to improve the overall efficiency of the transportation system. The underground space of urban transportation in various places is entering the period of rapid construction, and the depth and breadth of development have greatly increased, bringing a series of unprecedented problems and challenges. Based on the current development status of underground space of domestic transportation and policies, the advanced experience is summarized from multiple levels such as time, space and type, and the relevant problems and difficulties are sorted out. In response to the difficulties raised, the development countermeasures underground space of transportation are proposed. The overall thinking and countermeasures provide reference for the future development of underground space of transportation.
