摘要
在京津冀协同发展的进程中,城市空间从地上空间不断向地下空间延伸,对地下空间多尺度多参数的表达,利用空间模型进行评价、预测、开展决策支持提出了较高的要求。当前,城市三维地质模型的建设尚未形成系统、完整、全面的技术路线和规范,模型地质属性表达能力较弱,建模所需地质资料完整程度较低,模型应用主要是地质对象表达,虽然部分城市已用于地下工程设计,但总体应用层次较低。针对存在的问题,进行了三个方面的探索:首先,对国内外城市地质三维建模的进展进行了梳理,对采用的主要建模方法进行分类,对前沿应用进行归纳;其次,分析北京地质三维模型建设现状,提出系统建设的技术路线和应用框架,提出完善地质资料管理体系的建议;最后,选取京津冀协同发展热点区域通州副中心开展应用试点,探索建立多尺度多参数的三维地质模型,对模型应用进行探索,为后期应用设计提供灵活的数据接口,并为下一阶段建设提出技术、应用和政策等方面的建议。该研究为北京市建立地下资源环境三维模型进行了深入探索,为城市地质三维系统在京津冀协同发展过程中的城市规划、地下工程、空间资源保护的开发利用、环境保护和污染监测等方面的服务提出建议,为政府决策提供支持。
In the process of collaborative development of Beijing, Tianjin and Hebei, urban space has increasingly extended from surface to underground. Thus it requires the multi-scale and multi-parameter expression of underground space, and the evaluation, prediction, decision support using spatial model. Currently, it is not completely mature in urban 3-D geological modeling(U3DGM), the expression of geological attribute is not perfect yet, the utilization of U3 DGM is almost limited in model expression. Although U3 DGM has been used in underground engineering design, the utilization remains at elementary stage. This paper discusses the challenges in solving this problem, which include: 1) arrange the progress of U3 DGM, classify the methodology and the advanced applications of U3DGM; 2) analyze the current U3 DGM of Beijing, then propose the technology roadmap of construction and application framework of U3 DGM system, and the suggestion to geological data management; 3) select Tongzhou City Vice Center(the hotspot of collaborative development) as pilot regions, research the construction of the multi-scale and multi-parameter 3-D geological model and its application, design the flexible data interface for later use, and provide the suggestion of technology, application and policy for the later stage. This research serves directly the construction of Beijing 3-D underground resources environment model system, and provide suggestions of system application in urban planning, underground engineering, spatial resources exploitation, environment protection, pollution monitoring and government decision support.
