客运专线铁路桥梁振动实时监测技术研究

Research on Real Time Vibration Monitoring Technique for Railway Bridge on Passenger Dedicated Line

随着客运专线的发展,桥梁在高速铁路中所占比重越来越大,桥梁振动实时无线监测对于实时掌握客运专线铁路桥梁状态,保证列车的运营安全有重要的意义。本文结合兰新客专一座立交桥的4跨预应力混凝土梁振动的实时监测工作,阐述了研发的桥梁振动实时监测系统的组成与工作方法,前期准备工作及现场监测效果。

With the development of passenger dedicated line,the percentage of bridge in high speed railway is increasing. Real time wireless monitoring for bridge vibration is of great importance to control the bridge condition in time and ensure the operation safety of train.Based on the real time vibration monitoring of a prestressed concrete beam with 4 spans of a overpass on Lanzhou-Urumqi passenger dedicated line,this paper described the composition and working method of the real time monitoring system,the preliminary work and effect on field monitoring.
