基于应用场景的城市深部地下空间规划模式研究

Research on Planning Model of Urban Deep Underground Space Based on Application Scenario

地下空间开发利用是解决当前我国土地资源紧张、人口稠密、交通堵塞等诸多城市问题的一种重要途径,但当前浅层地下空间开发利用方式难以直接指导我国复杂的深地开发场景,探寻深地空间开发组织模式是我国新时期城市化发展的必然需求。通过梳理国内外深部地下空间应用场景,通过分析深地矿井、深地交通、深地储存、深地实验室等各类场景下相应空间特征以及使用需求等,总结提出了点状、线状、面状和立体网络式4种典型的深部地下空间网络组织模式,并分析4种典型发展模式的适用特征与可能的应用场景,以期为我国深地空间开发建设和场景设计提供参考借鉴。

The development and utilization of underground space is an important way to solve many urban problems in China,such as land resource scarcity,dense population,and traffic congestion.However,the current shallow underground space development and utilization methods are difficult to cope with the complex deep land development scenarios in China.Exploring the organizational model of deep land space development is an inevitable need for Chinas urbanization development in the new era.This article reviews the application scenarios of deep underground space at home and abroad,analyzes the corresponding spatial characteristics and usage needs in various scenarios such as deep mines,deep transportation,deep storage,and deep laboratories through case studies,summarizes and proposes four typical deep underground space network organization modes:point,line,surface,and three-dimensional network.The applicable characteristics and possible application scenarios of the four typical development modes are analyzed,in order to provide reference and reference for the development,construction,and scene design of deep underground space in China.
