铁路路基沉降预警系统构成及工程应用

Structure of the railway embankment settlement forewarning system and engineering application

摘要: 随着当前铁路建设的发展,大量的高速铁路不可避免地从软土、采空区、岩溶等地区穿过,其路基要求强度高、变形小。针对当前国内外路基变形监测手段不足,提出了铁路路基沉降预警系统,系统由传感器、CAN总线、计算机、数据采集与分析软件系统、报警器、VGA传输系统构成。通过对路基进行实时观测判断路基变形并提供警报,是保证路基稳定的重要手段。工程实践表明该系统能够实时地监测路基的变形并报警提示,具有成本低、安装简单、可靠性高、适用范围广泛等特点。

Abstract: With increasing development railroading,it was inevitably for a large number of high-speed railway transiting through settlement vulnerability areas underlying molsoil、cavities and karst region,where necessitated a real time monitoring system to alarm the risk of railway embankment deformation and settlement.To meet the demand of monitoring railway embankment deformation,this paper presented a forewarning system of railway embankment settlement,which was composed of a sensor,CAN bus,computer,data acquisition and analysis software,alarm and VGA transmission system.Engineering experiment practiced the function of real time monitoring and forewarning railway embankment deformation,with the feature of low cost,simple installation,high reliability and wide application.
