数字化隧道三维建模分析

摘要

In the paper,the technology of using structural model database to assemble tunnel is proposed,the classification of tunnel structure model database is presented,and the parameters of each structural model is designed.The specific processes of 3 D tunnel model building with 6 functional groups are presented.The input and output requirement and the effect of each group are analyzed.In the end,the prospects of the development of 3 D tunnel design software are proposed.%为解决既有隧道数字化三维建模的难题,提出利用构件模型库组装隧道的技术路线.整理出隧道构件模型库的分类,并完成各类构件模型的参数设计工作；提出由构件搭建三维隧道模型的具体步骤并将其固化为6个功能组,分析出每个功能组的作用、输入及输出等关键需求；提出继续开发三维隧道设计软件的构想.
