摘　　要：为解决隧道洞口工程设计因控制因素变化导致设计工作需多次反复、工作量大、传统设计方式效率低的问题,提出利用BIM技术在AutoCAD Civil 3D平台上研发三维辅助设计系统技术方案。通过对隧道洞口处dwg地形图进行预处理与识别,建立三维数字地形模型,采用部件编辑器与C#语言编程相结合的方式实现自定义部件,利用Civil 3D的“廊道”功能,实现隧道洞门参数化设计。通过对系统进行整体架构设计和关键模块设计,利用.NET API二次开发接口,研发铁路隧道洞口三维设计系统,并应用到隧道设计中。工程应用表明,该三维设计系统技术方案可行,系统结构设计合理,满足隧道专业设计需求。In order to solve the problems of repeated designs,heavy workload,and low efficiency of traditional design methods in engineering designing of tunnel portals due to changes in control factors,this paper proposes a technical solution by developing a 3D aided design system on the AutoCAD Civil 3D platform with the BIM technology.Based on preprocessing and recognition of the DWG topographic map at the tunnel portal,a 3D digital terrain model is built.The part editor is combined with C#language programming to realize parts customization,and the“Corridor”function of Civil 3D is used to realize parametric modeling of the tunnel portal.Through overall architecture design and key module design of the system,and using the secondary development interface.Net API,the 3D design system of railway tunnel portal is developed and applied to tunnel design.The engineering application shows that the technical solution is feasible,and the design of the system structure is reasonable and meets the design requirements of the tunnel profession.
