The Optimization Of The Space Construction In The High-speed Railway Station

The space construction in the high-speed railway station was studied in four aspects:the relationship between the site selection of the station and the urban space, the design optimization of the connection between the outside space construction of the station and the urban traffic system, the plane arrangement and the traffic organization in the station, the sustainable design in the station.In the aspect of the relationship between the site selection of the station and the urban space, the influence of the station site selection to urban space was studied, and the station classification system was proposed. Based on the analysis of the existing evaluation system on site selection, the new quantitative evaluation system was established with three factors:Performance of the density; spread performance; the OD performance.Then, the design optimization of the connection between the outside space construction of the station and the urban traffic system was studied. The coupling development models for different station were analyzed. The coupling process and the competitiveness for different kinds of coupling models were studied. The optimized coupling models for different grade of station were obtained in order to give suggestions for the general layout design of the high-speed railway station.Thirdly, the plane arrangement and the traffic organization in the station were discussed. The methodologies of Space Syntax and Geographic Information System were used in the design in order to optimize the passenger flow line in the station plane. Integrated with the obtained graph data for different grade of station, the detailed optimization suggestions and the optimized design models for different grade of station were obtained in order to provide directions for station plane design.At last, the sustainable design was analyzed. The sustainable design principles were proposed. Then, the status analysis of the sustainable design in large-scale public buildings was summarized. Integrated with the building characters of the station, the suitable sustainable design methods and technologies were suggested.In conclusion, this paper systematically discussed about the spatial construction and the optimal design in the high speed railway passenger terminal from several aspects, including the site selection, the site planning, the inner plane arrangement, the traffic streamline design, the sustainable design and etc; it also proposed the principles on both planning design and architecture design in the high speed railway passenger terminal, so it could provide with the guidance standards when the passenger terminal building came into reconstruction or it needed to design a new one.
