Rcscarch On Optimization Design Of Underground Space Of Urban Rail Transit Station Area

With our city’s social economy progress, and urban intensification of continuousimprovement, it has become an unstoppable tide that the development and utilization of theurban underground space resources, and opening up new urban space are driven by theconstruction of urban rail transit.But traditional single-function underground space of railtransit isn’t completely adapted to the fast pace of modern city and an increasingly rich citylife. It has become a trend that Urban rail transit Stations underground space gradually intothe development of comprehensive, intensive, and three-dimension.This will not only expandurban space, optimize the urban system, improve the urban environment, but also maximizethe transportation advantages of surrounding areas of rail transit station, and promote theprosperity and development of the region.By the construction of the rail transit in our cities, large-scale development and utilizationof underground space occurs in recent years. The development and utilization isn’t adequateor correct in the majority of the existing underground space of rail transit station areas.Themajor question is that it has single functional form, the scattered layout, obstruction trafficflow line, poor internal environment and so on.This article studies on the design of theunderground space of the station area. It could provide reference and complement for relateddesign practices and theoretical studies for the future.Firstly, it is summarized that the practical experience and their development trends ofdevelopment and utilization of urban rail transit station of underground space.Then it pointsout our cities problems in this filed. On the basis of research and analysis underground spaceof the basic functions, space-use patterns, characteristics of the internal environment as wellas the relevant factors affecting its development, it proposes optimization design goal ofunderground space of the station area. It put forward four aspects of the optimization designstrategfrom a functional organization, form layout, traffic convergence and internalenvironment. In order to Achieve the target that optimize the urban system, expand urbanspace, improve the transfer efficiency and improve the quality of space internal, it needsstrategies that is the organic integration of the functional elements，of the form layout ofaggregation, traffic organization and humanity internal environmentFinally, with XizhimenStation in Beijing as an example, it analyzes status with the proposed theories and methods toand put forward the corresponding optimization recommendations for the existing problems.
