【摘要】 为实现大瑶山隧道地表及地层的三维可视化,重点研究了工程中常用的AutoCAD格式的原始图形文件到地质建模软件所需的高效格式转换方法;以地表等高线和隧道地质剖面原始AutoCAD格式数据为基础,利用三维地质建模软件,建立了武广客运专线大瑶山隧道三维地表、地层和隧道模型。为今后隧道三维地层可视化的进一步研究与开发,奠定了良好的工作基础。更多还原

【Abstract】 In order to achieve 3D visualization of the ground surface and stratum of Dayaoshan tunnel,the following 2 topics are studied in particular in the paper: studying on effective format conversion methods so as to convert AutoCAD format graphics files,which are often used in engineering,into proper format files required by the 3D geological modeling software;Based on the AutoCAD format data of the contour map and longitudinal geological profile of Dayaoshan tunnel on Wuhan-Guangzhou passenger-dedicated railway,3D ground surface model,3D stratum model and 3D tunnel model are established for the tunnel by means of the 3D geological modeling software.The research lays a sound foundation for further study and development of the 3D visualization of the tunnel stratum in the future.更多还原
