The deepest 50 meters!Guangzhou plan for underground space

Recently, the first meeting of the 4th Guangzhou Municipal Planning Commission's urban transportation and municipal facilities committee was held to review and approve the "Guangzhou Urban Underground Space Plan" (hereinafter referred to as the "Plan"). Underground space, as an important strategic resource for the city, builds a ground space with composite functional, complete system, and security toughness. It is of great significance for promoting the high -quality development of cities, accelerating the new vitality of old cities, and "four new brilliance".

In terms of the overall layout of the underground space, the "Planning" is based on the "Master Planning of the Land Space in Guangzhou (2021-2035)", combined with the analysis of underground space demand, and the rail transit network as the skeleton, and the multi-line transfer (hub) site as the node coordinating The development of the underground space area forms a spatial structure of "one core, one network, and six pieces". One nuclear refers to the central urban area, which is the core area of ​​underground space development; a network refers to the planning rail transit network; six pieces are Huadu -Airport, Knowledge City, Conghua, Zengcheng, Panyu, and Nansha underground space development area.

The "Planning" also proposes that the urban underground space should follow the principles of layered use and from shallow to deep. It can be divided into four layers. The shallow layer is 0-15 meters, and the shallow layer is 15-30 meters. Buried depth of 30-50 meters, deep-buried depth> 50 meters. During the planning period, the development area focuses on shallow and secondary spaces, and the sub -deep space is appropriately expanded. Deep -seated space (except for local pile foundation needs) as the long -view development resources to protect and control. Local regions can appropriately increase the depth of underground space due to special needs, and areas with poor geological conditions need to take corresponding engineering measures.
