Current urban underground spaces face many problems
such as extensive development and low landuse efficiency. An intensive
underground comprehensive space is built to address these problems and promote
highquality development of infrastructure.
Accordingly, the integrated design practice and key techniques for underground
comprehensive spaces for the energy finance and trade zone in the new Xixian
area within Xi′an, China, are explained in detail. A
threedimensional space integrating municipal, traffic,
culture, commercial, and leisure functions is developed. The space includes:
(1) a multilevel integrated utility tunnel with trunkbranchcable along the urban road network; (2) an urban ring tunnel
connecting municipal roads and plots; and (3) a doublelayer
fourzone green corridor around the metro station in
the energy finance center using a transitoriented
development mode. Furthermore, the project connects every part of the
underground space to form a whole, and the utility tunnel and urban ring tunnel
are constructed separately at special inflection points. Finally, the
ventilation methods and evacuation plans are proposed without any targeted
design and construction standard guidance. The intelligent unified management
platform is used for joint control.
