摘　　要：针对复杂路线上大规模桥梁的三维建模以及工程信息输入工作繁琐、耗时、难度大的特点,提出了一种将两次法线定位法与使用共享单元相结合的解决方法。该方法可以方便地对道路沿线所有桩基、桥墩、承台、施工节段、护栏立柱、路灯等构件进行快速、精确定位,并能实现大规模桥梁部分构件的快速建模与批量工程信息输入。该方法已成功应用于多个工程项目的设计与施工信息模型创建过程中,经检验,该方法成果可靠,可以较好地提高工作效率。In this paper,a method of combining twice normal positioning with shared element is proposed according to the characteristics of tedious,time-consuming and difficult for information model creation of large-scale bridges on complex routes.It is convenient to locate all pile foundation,pier,bearing platform,construction section,guardrail column,street lamp and other components along the road quickly and accurately,and it can realize the rapid modeling and mass engineering information input of largescale bridge components.This method has been successfully applied to the design and construction information model creation process of many engineering projects,the results show that the method is reliable and can improve work efficiency.
