摘要
为在路线设计阶段提高线形设计的合理性,将空间曲率作为公路线形连续性的评价标准,采用VS开发工具及C#开发语言对Civil 3D进行二次开发.建立了以空间曲率为指标的评价模型,形成了针对线形连续性的公路线形评价程序,该程序可以作为扩展工具在Civil 3D中运行,并利用该程序对位于黑龙江省的骆驼砬子至庆有屯公路进行了线形连续性评价检验.结果表明,本文开发的公路线形连续性评价程序能够快速计算空间曲率,并对线形安全性做出评价,可为公路项目线形优化提供参考.
In order to improve the rationality of the alignment design at the route design stage, the spatial curvature was used as the evaluation standard of highway alignment continuity, by using the VS as the development tool and the C# as the development language, the secondary development of Civil 3 D was carried out. The evaluation model based on spatial curvature was established, and a highway alignment evaluation program for the continuity of alignment was developed, which can be used as an extension tool in civil 3 D. The program was used to evaluate the alignment continuity of Luotuolazi—Qingyoutun highway in Heilongjiang province. The results show that the proposed highway alignment continuity evaluation program can quickly calculate the spatial curvature and evaluate the alignment safety, which can provide reference for the alignment optimization of highway projects.
