在隧道施工中,地质灾害(涌水、塌方、岩爆等)的发生严重影响工程进度,增加工程造价,导致工程事故时有发生,因此在隧道施工中进行准确快速的超前地质预报是十分必要的。采用超前地质预报,结合常规围岩变形监测等多种手段,对隧道的围岩实现掘进面附近时空变形的预测和预报分析,并对隧道的衬砌状态进行评价,为施工设计提供指导性依据和现场监控手段,能够达到安全施工和优化设计目的。
In the tunnel construction, geological disasters (gushing water, landslide, rock burst, etc.) seriously affect the progress of the project, increase the project cost, lead to engineering accidents occur from time to time, so in the tunnel construction accurate and rapid geological prediction is very necessary . By means of advanced geological forecasting combined with conventional monitoring of deformation of surrounding rock and other means, the prediction and prediction analysis of the space-time deformation near the heading face of the surrounding rock of the tunnel is carried out. The lining status of the tunnel is evaluated, which provides an instructional basis for construction design and On-site monitoring tools, to achieve the safe construction and optimization of design purposes.
