自动化监测技术在铁路便梁施工中的应用

The Application of Automatic Monitoring System in the Construction of Railway Engineering Convenience Beam

铁路结构稳定与运营安全、舒适性紧密相关,外部施工对铁路影响的安全监测是保障铁路营运重要保障。为探究铁路结构监测点、工作基点与基准点布设的复杂情况,如监测点破坏、设站点的精度影响等因素,结合某铁路工程架设便梁对路基结构影响的实例,研究自动化监测系统在铁路保护区范围内安全施工的应用。依托该实例项目的监测设计方案,采用多周期的监测变形情况分析该系统在铁路结构监测中的优越性。结果表明:该区段的监测方案能够满足多股道、大面积监测的需求,能够为类似的监测项目在满足监测精度的条件下提供更加优化的建议。

The stability of railway structure is closely related to the operation safety and comfort.The safety monitoring of external construction impact on railway is an important guarantee for railway operation.In order to explore the complex situation of the layout of railway structure monitoring points,working base points and datum points,such as the damage of monitoring points,the influence of the accuracy of setting up stations and other factors,combined with the example of the influence of a railway project to the subgrade structure,the application of automatic monitoring system in the safe construction of the railway protection area is studied.Based on the monitoring design of the case project,the advantages of the system in railway structure monitoring are analyzed by using multi period monitoring deformation.The results show that the monitoring scheme of this section can meet the needs of multi track and large area monitoring,and can provide more optimized suggestions for similar monitoring projects under the condition of meeting the monitoring accuracy.
