BIM技术在机荷高速工程初步设计中的应用

Application of BIM Technology in Preliminary Design of Jihe Expressway Project

摘要:

以机荷高速公路改扩建项目为背景，针对BIM技术在初步设计阶段的应用进行研究。首先，在项目设计前面对专业众多、设计数据庞大问题，建立协同工作平台、创建统一工作空间及制定标准建模规则的技术构架；其次，为实现路线设计方案可视化分析和评价，对于道路设计过程中三维实景模型、管线及控制因素建模进行BIM技术论证，创建精细化场地模型；最后，以BIM正向设计为目的，在CNCCBIM OpenRoads 软件及路、桥、隧集成开发平台下，进行道路、桥梁、隧道重要设计技术节点研究。创建BIM在公路正向设计中的科学、合理应用工作流程，为后阶段BIM实现正向设计提供经验借鉴。

Abstract:

Taking Jihe Expressway Reconstruction and Extension Project as the background, the application of BIM technology in the preliminary design stage is studied. First of all, aiming at the professional numerous and huge design data before the project design, a collaborative work platform is established, the unified working space is created, and a technical framework of standard modeling rules is built. Secondly, to achieve visual analysis and evaluation of route design schemes, the 3D real scene model, pipeline and control factor modeling in the road design process are carried out for BIM technology demonstration, and a refined site model is built. Finally, for the purpose of BIM forward design, the important design technology nodes of roads, bridges and tunnels are studied in the CNCCBIM OpenRoads software and a road, bridge and tunnel integrated development platform. The scientific and reasonable application workflow of BIM in the forward design of highways is created, which provides the experience and reference for the realization of forward design of BIM in the later stage.
