摘　　要：监控量测在隧道信息化施工中至关重要,通过现场数据的采集、分析及反馈,建立预报信息系统,科学地预报隧道重大灾害具有重要意义。以厦蓉高速(贵州境)榕江格龙至都匀段计摆隧道格龙端左线洞口浅埋偏压段为研究对象,基于监控量测信息(收敛位移、拱顶下沉及地表位移等),及时分析并运用预报信息系统,成功预报了洞口段斜坡滑移趋势,及时调整设计和施工组织方案,有效控制险情进一步的发展,确保了隧道施工安全。Monitoring plays an important role in the information-based construction of tunnels.A forecasting information system is established on basis of field data collection,analysis and feedback so as to scientifically forecast the main disasters in the tunnel construction.Taking the shallow-buried asymmetrically-loaded portal section（on Gelong side） of the left tube of Jibai tunnel of Gelong-Duyun section of Xiamen-Chengdu expressway as the study object,the authors successfully forecast the slope slide tendency in the tunnel portal section on basis of the monitoring results （ convergence,displacement, crown settlement, ground surface displacement, etc. ） and the forecasting information system. Therefore, the design and construction organization plan of the tunnel are adjusted, the risk are effectively controlled and the tunneling safety are guaranteed.
