Research on Spatial Characteristics of Underground Transfer in High-Speed Railway Station Based on Spatial Syntax

As an important place for people evacuation, the use effect of underground transfer space in high-speed railway station will be affected by its own spatial organization characteristics. Beijing-Fuzhou high-speed railway is a part of the Beijing-Hong Kong (Taiwan) channel, one of the "eight verticals". Through field investigation, thirty-eight stations on the Beijing-Fuzhou line were investigated and divided into two types: network format and axis type according to the form of spatial organization. Hefei South Station and Xuzhou East Station are selected as two typical cases. Using the axis method and horizon analysis method of spatial syntax as as specific analysis means, combined with integration, connection value, intelligibility visual integration degree, visual control degree and visual aggregation coefficient. The accessibility, permeability, recognizability, visibility, field of view and limitation of underground transfer space are analyzed. The organizational characteristics of underground transfer space of the Beijing-Fuzhou high-speed railway are summarized, and corresponding optimization strategies are put forward.
