摘要
研究目的:交通枢纽内国铁与城轨作为两大功能主体,二者之间的换乘功能关系决定了枢纽体内在空间形态的生成及组织逻辑。本文通过大量典型案例的分析、概括与归类,展示交通枢纽内国铁与城轨之间不同换乘功能及其空间形态的多样化特征,并探寻其内在生成规律。研究结论:(1)交通枢纽内国铁与城轨的换乘空间形态大致可归纳为水平线性换乘空间、水平围合式换乘空间和竖向分层疏导式换乘空间,三种换乘空间形态在换乘距离、导向性及可识别性、突发客流疏解能力上分别各有所侧重;(2)换乘空间内的防火分隔形式对其空间连续性及视觉通透性存在一定影响;(3)换乘功能及空间形态的优化伴随着枢纽整体或局部规模及工程量的变化,设计需统筹兼顾;(4)本文的归纳研究可对后续交通枢纽项目中换乘空间的设计及再创新提供指引和帮助。
Research purposes: Railway and subway are two main functions of transportation hub,and the transfer function relationship between them determines the formation and organization logic of spatial form in the hub. Through the analysis,generalization and classification of a large number of typical cases,this paper shows the diversified characteristics of different transfer functions and spatial forms between railway and subway in urban comprehensive transportation hub,and explores its internal generation law.Research conclusions:( 1) The transfer space form of railway and subway in transportation hub can be roughly divided into three types: horizontal linear transfer space,horizontal enclosed transfer space and vertical layered and dredged transfer space,and the transfer functions served by different space forms have different emphases on the transfer distance,orientation and identification,and the ability of relieving sudden passenger flow.( 2) The fire separation form in transfer space has certain influence on its spatial continuity and visual permeability.( 3) The optimization of transfer function and spatial form is accompanied by the increase of the overall or local scale of the hub,so the design should be considered comprehensively.( 4) The research conclusion can provide guidance and help for the design and re-innovation of the transfer space of the subsequent transport hub projects.
