提升地下交通环廊利用效率的设计新思路

城市核心区的地下空间开发已经进入快速发展期,建设城市地下交通环廊是改善区域交通与环境的重要措施, 多应用于商务区、公共服务核心区等交通压力大、慢行环境品质要求较高的区域,是用于连接各地块地下车库并直接与城市道路相衔接。目前相关研究及规范对地下交通环廊功能定位、规划设计中应重点考虑因素的论证尚不成熟,且受政策、管理、规划设计、宣传等影响,已运营的地下交通环廊普遍存在运营效率不高等问题。本文重点从规划设计层面分析了环廊利用效率不高的原因,结合既有工程运营实践分析了既有设计规范的不合理点,并提出了规划设计新思路与新标准,并应用于西咸新区能源金贸区地下环廊规划设计实践,供行业实践及规范进一步修编参考。

A New Method to Enhance the Utilization Efficiency of Underground Traffic Tunnel

Urban underground space development has entered a rapid development period, the construction of urban underground traffic tunnel is an important measure to improve regional transportation and the environment. The traffic tunnel is used in the business district and the core area of public services. It is used to connect the underground garage and directly link up with the urban road. Current research and planning and design of underground traffic tunnel is not yet mature, and the operated underground traffic tunnel efficiency is not high. The paper analyzes the causes from the planning and design then puts forward new ideas and new standards. It is successfully applied to the underground traffic tunnel of Xixian New Area, which can provide reference for further industry practice and the revision of standard.
