深圳城市地下空间开发现状及典型工程案例分析

深圳是我国的经济特区和粤港澳大湾区的核心城市之一,在城市建设方面取得了显著成就,而随着地面空间越来越有限,开发地下空间成为深圳未来发展的必然趋势。本文首先综述了深圳在地下交通系统(包括轨道交通系统和地下快速道路)、地下综合管廊、地下商业中心及其他地下市政设施方面的建设现状及未来规划情况,并提出了深圳地下空间开发利用现状中存在的问题和不足。然后,结合几个深圳已建成或拟建的典型地下空间开发工程实例,介绍了几个不同类型的地下工程案例的设计与建设概况,分析了其中的技术创新及重难点问题。最后,针对深圳地下空间在统筹规划、开发程度、施工难度和政策法规等方面存在的不足,提出了关于深圳未来地下空间开发的几点建议。

Current Status and Typical Case Analysis of Urban Underground Space in Shenzhen

Shenzhen is China's special economic zone and one of the core cities of Guangdong, Hong Kong and Macao. Significant achievements have been made in Shenzhen's urban construction. With the urban ground space of Shenzhen becoming more and more limited, the development of underground space has become the inevitable trend. This paper first summarized the current status, the future planning and the existing deficiencies of underground space construction engineering in Shenzhen, such as underground transportation system (including underground rail traffic system and underground expressway), utility tunnel, underground commercial street and other underground municipal facilities. Secondly, combined with several typical underground space development projects which have been completed or planned in Shenzhen, the design and construction overview was introduced, and the difficulties and technical innovation in these projects were analyzed. Furthermore, based on the existing deficiencies in overall planning, development level, construction difficulty, policies and laws of the urban underground space utilization in Shenzhen, some thoughts and suggestions on the construction of urban underground space in Shenzhen were put forward.
