超高过渡段路基边线空间设计方法研究

Study on Space Design Method of Roadbed Sideline for Super-elevation Transition Section

近几年BIM技术在国内得到重视且发展迅速,从国家政策制定到地方技术实施对BIM技术的认识在逐步清晰,越来越多的BIM技术应用成果落地进一步证实了BIM技术在国内的推广价值。BIM技术的应用为市政路桥建设行业的技术升级及服务转型带来希望。设计单位从BIM设计入手解决了实际设计工作需求,但限于目前BIM软件技术的局限性,有些功能尚无法实现,需要设计人员与软件开发人员共同研究,提出现阶段可适用的技术解决方案。因此以道路工程BIM设计中超高过渡段路基外侧边线(空间边线)为例,系统对比了2D、3D设计方法的区别及设计过程,并对2种设计成果进行了对比分析,可为其他类似BIM设计方法提供解决思路。

In recent years,BIM technology has received attention in China and developed rapidly.Engineers have gradually become clear about BIM technology in making of national policies and practice of local technologies.The promotion value of BIM has been confirmed by more and more BIM technology has been successfully applied.It provides support for technological upgrading and service transformation in the municipal construction industry.Design units have solved some problems of BIM in the design process.However,due to the limitations of BIM software,it is necessary for engineering designers and software developers jointly research to find feasible solutions to some impossible functions.Taking the outer edge(spatial edge)of the subgrade at the super-elevation transition section as example,the author compares the difference between 2D and 3D design methods.The research results can provide solutions to other similar BIM designs.
