摘　　要：随着北京地铁建设的飞速发展,对于地质情况、地面建筑及地铁结构的资料的合理利用和整合成为地铁建设领域的一个热点问题。三维地质建模技术以其强大的实时建模功能及展示功能成为解决这一难题的重要手段。利用北京大学信息地质研究实验室开发的小场景建模系统(Creatar Project Explorer)对在建的北京地铁六号线车公庄西站工程进行了地质体、地铁结构及地面建筑物的建模,并进行了三种模型的联合展示,展示的结果表明,小场景三维地质建模技术能准确直观地反映地面建筑、地铁结构及地层的空间关系,方便建设人员对地铁信息、结构信息实现高效的管理。这些研究成果也为三维地质建模技术在地铁建设过程中的应用提供了借鉴。With the rapid development of subway construction in Beijing, reasonably applying and imegrating in- formation of geology and surface buildings as well as underground structure has become one of the hot issues in the field of subway engineering. And 3D geological modeling system with its powerful real-time modeling capabilities and visualization capabilities becomes an important method to solve this problem. Small seene 31） model syste,n （C,＇eatar ProjeetExplorer） developed by Peking Ceologieal Research Laboratory is used to model geological body , subway stmchu＇e and surface buildings of Chenggongzhuang west station of subway line six in Beijing. Furthermore, the lhree models are jointly displayed. The resuh shows that 3D geological modeling techniques can reflect spalial relatiouships among surface tmihtings, subway structures and geological body accurately and intuitively. So it is more convenienl for builders to manage the information of subway Stnleture effic.iently. The results of these studies also provide a refer- ence to applieation of the 3D geological modeling techniques into subway construction.
