济南泉域岩溶地区多源多尺度数据三维耦合模型及应用

为解决济南城市轨道交通建设与地质环境、保泉供水及建构筑物之间的矛盾，实现泉水保护与轨道交通建设双赢，研发了三维城市地质信息管理与应用系统。根据济南泉域富水岩溶的特点，采用现场工作、室内实验、理论研究、数值分析、成果集成应用等综合研究方法，设计了基于MapGIS 10的三维地质环境信息系统，建立了济南城区标高-350 m的三维可视化地质模型、岩溶模型和水位动态模型，形成了岩溶区三维地质建模的系统方法。为济南轨道交通建设及保泉供水提供了重要管理和应用平台，为济南城市轨道交通的规划、建设、管理提供决策依据，作出更科学的分析和预测。

Three-dimensional coupling model of multi-source and multi-scale data and its application in karst zone of Jinan spring region

In order to solve the contradiction between Jinan rail transit construction and its geological environment, protecting spring water supply and construsting buildings, and to realize the win-win of spring water protection and rail transit construction, this paper developed a three-dimensional urban geological information management and application system. Based on the characteristics of water-rich karst in Jinan spring area, and the comprehensive research methods of field work, laboratory experiment, theoretical research, numerical analysis and result integration application, this paper designed the MapGIS 10-based 3D geological environment information system, established the 3D visualization geological model of Jinan urban area, karst model and water level dynamic model (-350 m), and presented a systematic method for 3D geological modeling. It provides an important management and application platform for Jinan rail transit construction and protecting spring water supply, and a decision-making basis for the planning, construction and management of Jinan rail transit, which contributes to more scientific analysis and prediction.
