基于空间句法的高铁站域地下空间连通整合性能研究

Optimization of underground space connectivity and integration surrounding high-speed railway station based on space syntax

随着高速铁路的蓬勃发展,高铁站域地下空间的连通整合问题成为影响通行效率的重要因素之一。然而,当前研究多从定性分析出发,缺乏针对空间内部的系统性定量研究。基于此,文章以高铁站域地下空间的连通整合性能为主要研究对象,结合其特征属性确定研究范围,以空间句法为主要定量分析方法,构建了高铁站域地下空间连通整合模型,通过对现有案例的建模提出了两方面的优化方案,并进行了进一步的对比研究。研究表明:1)连通中心对于站域地下空间连通性能提升呈现较强的整体性;2)连通主轴对于站域地下空间连通性能提升呈现较强的局部性;3)高铁站域地下空间布局中可以考虑将连通轴与连通中心组合布置以提高连通能力。本文内容可为国内外高铁站域地下空间开发及连通整合性能提升提供参考。

The construction of high-speed railways is now in full swing,and the connectivity and integration of the underground space surrounding high-speed railway station has become one of the most important factors affecting the traffic efficiency.The current research mostly starts from qualitative analysis,lacking in systematic quantitative research on the interior of the space.Based on that,the research objects are mostly focused on the urban spatial analysis at the macro scale.Therefore,this study focuses on the connectivity and integration planning of the underground space of the high-speed railway station,the research scope of the underground space of the high-speed railway station is determined by referring to the existing research,space syntax is used as the main research method,and depthmap is used as the main spatial analysis tool to build a model,selects suitability indexes to measure connectivity performance,and two optimization schemes for comparative research are proposed through the modeling research of existing cases,which are further comparatively compared.The results show that:1)The connectivity center exhibits a strong overall effect on improving the connectivity performance of underground space surrounding high-speed railway stations;2)The main axis exhibits a strong local effect on improving the connectivity performance of underground space surrounding high-speed railway stations;3)In the layout of underground space surrounding high-speed railway stations,it can be considered to combine the connecting axis with the connecting center to improve the connectivity performance.This paper could provide relevant suggestions for the connection and integration of underground space in the high-speed railway station area.
