重庆市主城区地下综合信息评估及管理

为支撑重庆市主城区地下空间专项规划的实施,为其提供丰富的数据支撑,运用地质调查、地理信息分析评估及三维地理信息系统等相关方法对重庆市主城区5 473 km~2范围内地下空间现状进行了研究、评估,并实现了该范围内地下空间多源数据的综合管理.结果表明:①多源地下空间数据综合分析,才能有效地为地下空间专项规划实施提供依据;②综合地质条件分析发现,该区域约80%的区域适宜进行地下空间开发;③截止2017年底重庆市主城区地下空间开发利用总规模约为7 151万m~2,其中地下交通设施占比约为90%;④利用多源地下空间三维数据集成管理模式,不仅可以满足区域内地下空间现状数据的宏观管理,更能通过可视化模拟分析指导实际工程的设计、建设和评估.

Assessment and Management of Underground Comprehensive Information in the Urban Area of Chongqing

In order to provide abundant data support for the special planning of underground space in the main urban area of Chongqing, a study was made of the status quo of underground space within 5473 square kilometers of the main urban area of Chongqing with the methods of geological survey, geographical information analysis and evaluation and 3DGIS, and comprehensive management of the underground space multi-source data within this area was realized. The results obtained were as follows. Comprehensive analysis of multi-source underground space data can effectively provide a basis for the implementation of special underground space planning. According to the analysis of the comprehensive geological conditions, about 80% of the area is suitable for underground space development. By the end of 2017, the total scale of underground space development and utilization in the main urban area of Chongqing is about 71.51 million square meters, of which underground transportation facilities account for about 90%. The multi-source underground space three-dimensional data integration management mode can not only meet the requirements of regional interior spatial status data macro management, but also guide the actual project design, construction and evaluation through visual simulation analysis.
