广西乐百弄衣隧道企业级BIM技术应用

广西乐百弄衣隧道属于特长隧道，在隧道施工过程中，由于地质构造异常复杂，对于质量、安全的控制非常严格。隧道开挖的地质预报资料尤为重要，需排除前方不良地质、水纹条件，同时，隧道开挖过程中的超挖、欠挖工程量统计成为了传统施工的一个难点。此外，隧道的不均匀沉降监测数据实时记录更新及现场进度、质量、安全等均急需新型项目管理工具来辅助提升协同管理效率。针对以上隧道的施工重点难点，团队经过多次不同BIM系列软件的比对分析，采取了Revit+Dynamo+Civil3D+BIM5D的BIM解决方案，可解决从BIM模型搭建到项目各阶段的管理应用难题，如：清单工程量统计分析、以日为基准单位的施工进度管理、按每延米桩号定位辅助解决施工质量安全问题等等。利用本隧道BIM解决方案可根据现场施工实际信息数据进行深化模型，并多方位多角度辅助解决各类传统隧道施工的难点。本项目课题研究的成果可供类似公路工程BIM应用提供专业的技术解决参考方案。

Enterprise-Level Application of BIM Technology in Lebainongyi Tunnel Project in Guangxi

The Lebainongyi Tunnel is a super-long tunnel. During the construction of the tunnel, considering the complicated geological structure, the quality and safety of the tunnel are strictly controlled. The geological prediction data of tunnel excavation is particularly important, which is necessary to eliminate the adverse geological water-mark conditions in front. At the same time, the statistics of over-excavation or under-excavation quantities in the process of tunnel excavation has become a difficult point in traditional construction. In addition, new project management tools are urgently needed to help improve the efficiency of collaborative management, such as real-time recording and updating of tunnel uneven settlement monitoring data and on-site progress, quality and safety. In view of the above key difficulties in tunnel construction, the project team adopted the BIM solution of Revit + Dynamo + Civil 3D + BIM 5D after several comparisons and analyses of different BIM software series, which can solve the management and application problems from BIM model construction to various stages of the project, such as statistical analysis of bill quantities, construction schedule management based on the daily standard unit, positioning by pile number per extended meter assisting solving the construction quality and safety problems, and etc. The BIM solution used by the tunnel project is able to deepen the model according to the actual construction information data, and to help solve the difficulties of traditional tunnel construction in multi-direction and multi-angle. The research results of this project can provide professional technical solutions for similar highway engineering BIM applications.
