公路隧道辅助设计软件的新思路研究

研究了现有公路隧道辅助设计软件的思路和技术特点,结合公路隧道设计过程的实际需要,提出了公路隧道辅助设计软件的新思路,即建模和出图采用参数式与交互式相结合,计算、优化与出图集成统一。这些思路已经在作者开发的公路隧道设计软件中实现,证明了技术的可行性。该软件在同济曙光软件平台上开发,具有修改、实时更新的图形建模和出图功能,结合施工过程的有限元及其它数值方法的分析计算功能,并采用遗传算法等多种优化方法对结构进行最优化设计,具有后处理显示、可视化图纸管理、图纸库等功能。该软件能使整个公路隧道设计、计算、出图在统一的环境下完成,能有效提高公路隧道设计的效率。

New Thinking in Effective Highway Tunnel CAD Design Software

Based on the studies into existing highway tunnel CAD design software,and the requirements from practical highway tunnel design,some new solutions for CAD design software is presented.Firstly,to combine parametric based design and interactive design together in modeling and drawing. Secondly,to integrate the three subsystems together,which are structure calculation,structure optimization and construction drawings automatically generating.These solutions are applied in a highway tunnel design software and proved right.The software is developed on GeoFBA2D platform,and provides following features: parametric drawing and interactive drawing,updating drawing right on modification of parameters,FEM calculating considering construction stage,provides several optimizing algorithms and visual drawing management.Highway tunnel design,calculating,optimization and drawing can be completed in a integrated environment,so that highway tunnel design can be more efficiently.
