隧道安全风险管理系统在高铁隧道工程中的应用研究

Study of Application of Tunnel Safety Risk Management System to High-speed Railway Tunnel

依托某高铁隧道施工概况,基于安全风险开发隧道监控信息化系统。该系统基于现场检测组网的理论基础,包括检测数据的采集传输、管理分析及远程接收子系统等部分,运用该系统对隧道围岩变形、锚杆应力、围岩与钢架之间喷锚混凝土应力开展全天候的实时监测,形成监测量程应变、应力及压力时程曲线。该系统对隧道进行超前地质预报检测和环境净空扫描检测,及时掌控隧道地质情况和环境安全,为隧道施工方案调整和变更提供更有效的依据,增加了现场管控的时效性。

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 rockdeformation, 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 conditionscan 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.
