地下街与城市的融合与利用--以日本下沉广场及成都天府广场为例

Integration and Utilization of Underground Street and City--A Case of the Sunken Square in Japan and Tianfu Square in Chengdu

地下空间的开发利用已逐渐成为当前城市规划设计的关键因素。在中国,如何在地下空间引入自然光和周围环境值得探讨。本文以日本城市下沉广场为研究对象,通过案例分析和比较研究,探索下沉广场的多功能处理,研究如何更好地将地下空间的入口和出口与地面及其周围环境整合在一起,发挥采光和通风的作用,引导人流和分配交通,实现地下空间的整合与紧凑性,并以成都天府广场为例,进行分析与策略研究,为我国地下空间三维紧凑性的开发利用提供参考价值和思路。

The development and utilization of underground space has gradually become a key factor in current urban planning and design.In China,how to introduce natural light and surrounding environment into underground space is worth exploring.This article Taking the sunken square in Japanese cities as the research object,,this paper explores the multi-functional treatment of sunken square,and studies how to better integrate the entrance and exit of underground space with the ground and its surrounding environment so as to give full play to the role of daylighting and ventilation in guiding and distributing people and traffic flow and create a more integrated and compact underground space through case analysis and comparative research.Taking Chengdu Tianfu Square as an example,this paper also analyzes and studies strategies,aiming to provide reference and ideas for the development and utilization of the three-dimensional compact underground space in China.
