Abstract

The invention provides a high-speed rail tunnel operation period rail monitoring system and method, and relates to the technical field of high-speed rail seismic signal monitoring. Factors such as the real-time performance of operation monitoring data, the flexibility of a monitoring route and the comprehensiveness of a monitoring range are considered, and monitoring rails are arranged in the longitudinal direction and the circumferential direction for mobile monitoring of the monitoring device; a line between two annular monitoring rails is set as a section of monitoring line unit, and two monitoring modules in a monitoring module group start from two ends of the rails, move at the same speed at the same time and finally arrive at the end point of the line at the same time; a central control platform transmits a control signal to a monitoring module, the monitoring module operates and wirelessly transmits high-speed rail seismic signal data to a monitoring signal receiver through a wireless broadband detector, and the monitoring signal is processed and stored and transmitted to the central control platform; and after the monitoring signal is processed, the monitoring signal is transmitted to an early warning center through the central control platform, and when relevant parameters of certain monitoring data exceed threshold values, the early warning system gives an alarm.

Description

technical field [0001] The invention relates to the technical field of high-speed rail seismic signal monitoring, in particular to a track monitoring system and method during the operation period of a high-speed rail tunnel. Background technique [0002] High-speed rail is a repeatable artificial seismic source. During the operation period, the vibration generated by high-speed rail travel has an impact on roadbeds, bridges, tunnels, and surrounding buildings. With high-speed rail earthquakes and environmental changes, tunnel support structures may age. A certain range of damage or even destruction may occur inside the rock. Therefore, the monitoring of surrounding rock in the operation of high-speed railway tunnels is very important, especially for tunnels or extra-long tunnels passing through poor geological conditions, broken surrounding rocks, and alpine regions, such as Liaoxi Tunnel, Daliangshan Tunnel, Fengshun Tunnel, etc. In the operation of the tunnel project, it ...
