| 摘 要： | 基于BIM的道路全数字三维地质地面信息模型构建是实现道路工程BIM动态设计的关键。以北京市平谷区黄松峪山区某道路工程为例,将道路地质地面信息导入到Civil 3D中,利用Civil 3D的点、块、曲面、实体提取等功能,构建了三维地质地面信息基础模型并在此基础之上进行综合设计,实现了基于地质地面信息的纵断面设计、土石方计算等定量分析。结果表明,该方法可以初步解决道路设计中地质地面信息储存、管理、分析以及可视化的问题,为基于BIM的道路全数字化正向设计提供支撑。

| Abstract: | The digital 3 Dgeological ground information modelling based on BIM is the key to realize the dynamic design of BIM for road engineering.In this paper a road project in Huangsongyu mountainous area of Beijing Pinggu District is taken as an example.The geological and ground information are bring into civil 3 D,the point,block,surface,solid extraction and other functions of civil 3 Dare used to build a basic3 Dgeological ground information modeling and comprehensive road design based on the model.The quantitative analysis of vertical section design and earthwork calculation are realized based on the modeling.The results show that this method can solve the problems of geological ground information storage,management,analysis and visualization in road design,and support full digital forward design of road based on BIM. |
