随着现代城市轨道交通工程的复杂性和规模不断增大,对隧道施工精细化管理的需求也越来越迫切.本文以重庆轨道交通15号线的铜锣山隧道为工程背景,首先对UWB(Ultra-Wide Band)定位技术和BIM(Building Information Modeling)技术二者融合应用的可行性进行了研究,设计并实现了可视化融合定位系统,最后在工程实践中验证了该方法的有效性.研究表明,基于BIM与UWB的融合定位技术可以有效提高隧道施工管理精度、降低施工潜在风险、实现优化利用资源,达到精细化管理要求,具有较为广阔的应用前景.
Application of Integrated Positioning Technology Based on BIM and UWB in Fine Management of Tunnel Construction
With the increasing complexity and scale of modern urban rail transit engineering,the need for fine management of tunnel construction is becoming more and more urgent.This paper takes the Causeway Mountain Tunnel of Chongqing Rail Transit Line 15 as the engineering background.Firstly,the feasibility of the fusion application of UWB(Ultra-Wide Band)positioning technology and BIM(Building Information Modeling)technology is studied,and then the visual fusion positioning system is designed and realized.Finally,the effectiveness of the method is verified in engineering practice.The research shows that the integrated positioning technology based on BIM and UWB can effectively improve the accuracy of tunnel construction management,reduce the potential risks of construction,optimize the use of resources,and meet the requirements of fine management.It has a broad application prospect.
