摘　　要：城市是建设在地质体之上的,这就注定城市的建设发展离不开地质工作的支撑。城市三维地质建模是三维信息技术在城市地质领域的一个典型应用,可大大提升城市地质调查成果的表达方式,提高城市地质资源环境的评价预测能力,对中国正在大力实施的城镇化建设具有重要支撑作用。对城市三维地质模型进行了分类,分析了城市三维地质模型的特点;研究了城市三维地质模型的构建,并对城市三维地质结构模型的构建进行了详细阐述;以北京市为例,给出了城市三维地质建模服务城市规划、地铁隧道选线施工、新城建设、重点工程选址、资源开发等方面的应用实例。As cities are constructed on geological objects, the support of Urban Geology（UG） is necessary for the city construction and development. Urban 3-D geological modeling（U3DGM）, a classic application of 3-D information technology to UG, plays an important role in improving the UG achievement expression and urban geological resources and environment assessment. In addition,it may play an important role in supporting the ongoing urbanization in China. In this paper, the authors firstly make a classification and characteristic analysis of urban 3-D geological models. Secondly, the construction of urban 3-D geological models is studied,with more details given to the construction of urban 3-D geological framework models. At last, on the basis of the research in this paper, the applications of U3 DGM in the city plan are presented in such aspects as subway and tunnel location, new town construction,key projects location and resource development of Beijing.
