Abstract

Abstract:

A informatized tunnel monitoring system is developed based on security risk for a highspeed railway tunnel. The system is based on existing site monitoring theory and includes monitoring data acquisition and transmission, management and analysis and longrange receiving subsystem. The realtime monitoring on tunnel surrounding rock deformation, anchor bolt stress and shotcrete and anchor stress between surrounding rock and steel frame is carried out; and timehistory stress, strain and pressure curves are obtained. The geological conditions and environment conditions can be known by using the system to carry out advanced geological prospecting and environmental clearance scanning, which can provide reference for construction scheme adjustment and improve site management efficiency.

Key words: railway tunnel, monitoring, security risk, intelligent sensor, clearance scanning
