BIM技术在地铁车站下穿既有地道桥施工中的应用研究

Study on the Application of BIM Technique in the Construction of Underground Station Under the Underpass Bridge

地铁车站的建设施工涉及进度、成本、质量、安全等多维度问题,基于施工组织困难、周围环境复杂的施工现状,对工程项目进行信息化和精细化管理显得尤为重要。基于哈尔滨地铁3号线哈平路地铁车站下穿既有地道桥施工项目,采用BIM技术和有限元分析联合深化设计方案,提出一种基于BIM技术的城市地铁车站建设施工联合设计管理方法。工程实践结果表明:BIM技术在三维可视化设计和施工方案优化等方面均表现出了精准、高效的管理水平。所建立的基于成本和进度的5D集成化管理平台实现了工程多维度信息的高效传递,不仅提高了管理效率,还可以确保施工过程安全有序地进行。为以后类似工程实践提供了新思路,在地铁项目施工组织管理等方面有着较大的应用价值。

Construction of underground station is a multiple-dimensional problem relating to progress,cost,quality and safety.It is especially important to conduct information-based elaborate management since the construction organizing is difficult and the surrounding environment is complex.Based on the underground station construction under the underpass bridge of Haping Road project in Harbin metro line 3,the BIM technique is combined with finite element analysis to propose a BIM-based joint design management method of urban underground station construction.The engineering practice results show that the BIM technique performs accurately and efficiently in 3-D visualization and construction optimization.The developed 5-D platform based on cost and progress realizes the efficient transition of multiple-dimensional engineering information,which promotes the management efficiency and ensures the safety of construction process.The proposed joint design method based on the combination of BIM technique and finite element analysis provides a new way for other similar engineering practices,which has relatively large application value in the organization management of underground construction.
