基于BIM的山岭隧道施工信息化管理系统研发与应用

隧道施工现场采集的结构、地质、施工信息碎片化严重，缺乏统一组织手段，分析利用难度大，隧道动态设计与信息化施工水平有待提高。为支撑隧道工程施工信息化，对施工数据进行标准化定义，开发数据标准化工具，以支撑施工期异构数据统一组织应用。针对BIM技术在设计与施工中难以落地、工程数据难以集成的问题，研究多尺度BIM模型建立方法，并以里程为索引，集成地质、进度、设计方案等信息，实现施工数据统一管理与可视化。基于动态更新的施工现场数据与轻量化BIM模型，建立以集成信息模型为核心，桌面端、网页端与移动端应用综合服务的施工信息化管理系统，提供全面施工决策信息，动态评估施工风险，保障工程效率与安全。经云南老营特长公路隧道工程实践验证，本系统基本满足信息化管理需求，对隧道工程信息化管理及BIM技术的工程应用具有借鉴意义。

Development and Application of a BIM based Informationized Management System for Mountain Tunnel Construction

The structural, geological and construction information collected from tunnel site is seriously fragmented, lacking a unified organization framework, thus leading to the difficulty of analyzing and utilizing. The dynamic design and informationized construction of the tunnel should be improved. To enhance tunnel construction informatization level, the construction data organization standard is defined, a standardization application is developed to support the unified organization of heterogeneous data. To improve the application of building information modeling (BIM) technology in tunnel and data integration level, a multi scale BIM model is established, in which geology, schedule, design plan and other information are indexed by mileage. Through a standardized tool, the unification of construction data management and visualization can be realized. Based on the dynamically updated construction data and lightweight BIM model, a construction information management system with integrated information model as the core and integrated desktop, web and mobile applications is established to provide comprehensive information for decision making and construction risk dynamic evaluation, which ensures project efficiency and safety. Finally, the system is applied to Laoying extra long highway tunnel in Yunnan, and the applicable results prove that the system can meet the requirements of informationized management of tunnel construction The results can provide reference for the informationized management of tunnel engineering and the application of BIM technology.
