摘要
传统设计技术在路网优化设计项目中存在处理数据烦琐易错、二维表达不够直观等问题。针对传统技术存在的问题,提出了基于GIS的;BIM技术路网偉:化设计方法,GIS技术提供整个空间的三维可视化分析,极大地改善了BIM技术对外部环境信息分析不足的问题。以唐桂新城路网优化为例,使用GIS与BIM技术对该路网进行优化设计,按照“模拟-评估-反馈-优化”的渐进式优化思路,实现了优化后的路网与地形、周边地理环境、现状水系的结合更为合理,取得了良好的经济效益与环境效益。
In the road network optimization design project,the traditional design technology has some problems in the data processing,such as cumbersome and easy to make mistakes and two-dimensional expression not intuitive.Aiming at the problems existing in traditional design technology,this paper puts forward BIM technical road network optimization design method based on GIS.GIS technology provides 3D visualization analysis of the whole space greatly to improve the insufficient analysis of external environment information hy BIM technology.Taking the road network optimization of Tanggui New City as an example,this paper introduces the optimization design of this road network hy GIS and BIM technologies.According to the"simulation-evaluation-feedback-optimization"progressive optimization idea,the combination of road network with landform,surrounding geographical environment and current water system is more reasonable after optimization.The good economic and environmental benefits are achieved.
