城市门户型互通立交方案与景观效果研究

Research of Urban Portal Interchange Scheme and Landscape Effects

以粤东某城市门户型互通立交改造设计为例,介绍设计过程中形成的简化互通方案、完全互通方案、半互通集中上下方案、半互通分开上下方案4个代表性互通立交方案,并针对立交空间形态特点配套提出了“显”和“隐”2种景观提升策略,综合对比功能性、景观性、协调性、经济性等,得到交通与景观协调的最优方案。该研究表明,城市门户型互通立交设计在实现基本交通功能的同时,还应考虑城市风貌融合与地块综合开发,为同类工程项目提供设计思路。

Taking the renovation design of certain urban portal interchange in eastern Guangdong as an example,this paper introduces the four typical interchange schemes gradually formed during the research process:simplified interchange scheme,complete interchange scheme,partial interchange centralized up and down scheme,and partial interchange separated up and down scheme,as well as the two landscape improvement strategies of "visible" and "hidden" proposed based on the spatial characteristics of the interchange.Through comprehensive comparison of functionality,landscape,coordination and economy,the optimal solution for coordinating transportation and landscape is obtained.This study indicates that the design of urban portal interchanges should not only achieve basic transportation functions,but also consider the integration of urban style and comprehensive development of land parcels,providing design ideas for similar engineering projects.
