The massive volume of ground depot construction often
has adverse effects on integrating urban traffic and public landscapes,
restricting urban planning. With the increasing requirement of city development
on the public environment, the multispace integrated design of the
building above ground for the underground depots becomes more and more
important in improving the urban public environment quality, enlarging the
ground construction scale, and improving the landintensive
utilization and output efficiency. In this paper, a case study is conducted on
the vehicle depot design of the Shenzhen metro line 13, and the underground
depot + superstructure above depot mode and the feasibility of sinking the
metro depot and the multispace integrated design of
the building above ground for the underground depot are discussed from the
aspects of continuous design of superstructure above depot with the urban
landscape and road traffic, design difficulties of underground vehicle depots,
and the influence on cost and operation and maintenance. The main researches
and conclusions are as follows. (1) After the depot sinks, the integrity of the
urban land can be protected in maximum, the construction scheme of the property
building above depot and the transportation organization design can be
benefited, the adverse effects on the urban landscape fragmentation can be
reduced, and the urban public environment can be improved. (2) The sunk depot
can provide lateral constraints on the structure of the overlying buildings,
and the development and design orientation of the overlying buildings can be
more flexible, which can improve the height of the buildings and increase the
utilization rate of land. (3) The firefighting in
underground vehicle depot is a crucial and challenging point, whereas there is
no mature experience for reference at present. The structures such as ground
passageway and the fire fighting passageway have a significant influence on the
integrity of the building land above the depot, hence, it needs overall
planning, continuous exploration, and practice. (4) The construction of
underground depot will increase the project cost and construction risk to a
certain extent. (5) The planning and design of underground depot and above
buildings should be fully and carefully considered. (6) In the late operation,
adverse factors such as humidity, flood season, and fire should be rationally
dealt with, and the health of the workers in the underground enclosure space
should be guaranteed.
