Design and Realization of Bed Slab Monitoring Scheme for High-Speed Railway Based on BIM

高铁道床板服役状态监测是保障铁路安全运营的重要技术手段,针对传统监测方案在设计和实施过程中存在的难理解、不合理、效率低等问题,本文借助BIM技术,从监测需求分析、监测设备布点布线设计、监测数据管理平台的建立着手,研究了双块式无砟轨道道床板监测方案的设计和实现方法。实际应用结果表明:利用BIM模型可以精确排布监测设施,降低方案设计难度;通过碰撞检查可以发现方案中存在的问题,确保设计方案的合理性;动态施工模拟能够有效指导实际作业,保障方案的高效实施;通过数据管理平台可以查询实时数据,实现对轨道结构服役状态的可视化监测。

The monitoring of service condition of high-speed rail bed plate is an important technical means to ensure railways'safety operation.In view of the problems such as difficult to understand,unreasonable and low efficiency in the design and implementation of the traditional monitoring scheme.Under the help of BIM technology,this paper examines the design and implementation of the monitoring scheme of double-block ballastless track bed plate from the analysis of monitoring requirements,the design of monitoring equipment distribution points and wiring,and the establishment of monitoring data management platform method.The practical application results show that:the BIM model can accurately arrange the monitoring facilities and reduce the difficulty of the scheme design;the collision check can discover the problems in the scheme and ensure the rationality of the design scheme;the dynamic construction simulation can effectively guide the actual operation and guarantee the efficient implementation of the scheme;the data management platform can query the real-time data and achieve the visual monitoring of the service status of the track structure.
