摘要/Abstract

摘要： 在岩溶强发育地区隧道信息化施工过程中,存在涌水涌泥、塌方等地质灾害的高风险,给施工安全带来了重大灾难和无法估计的经济损失.本文在高风险岩溶隧道地质灾害综合预警预报方法研究的基础上,结合隧道超前地质预报“三结合”原则,利用综合超前地质预报技术对隧道开挖前的地质灾害进行综合预报,利用监控量测技术对隧道开挖后的围岩因大变形而导致的地质灾害事故进行预警,以高风险特长岩溶隧道为例,将超前预报和监控量测相结合对高风险岩溶隧道地质灾害,如大型塌方、涌水涌泥等地质灾害进行了成功的预报预警,避免了人员伤亡和重大经济损失.所采用的灾害预报技术手段和所提出的预警机制及方法及对类似工程具有一定的借鉴与指导意义.

Abstract: High risk of geological hazards such as landslide, burst mud and spring water often occur in karst areas during the informational construction of a tunnel, which can bring momentous disaster and unknown economic loss to construction safety. The precise and immediate forecast for the geological hazards, and how to make it under effective control were the key problem to be researched and resolved currently in tunnel dynamic designation and informational construction in karst areas, which can bring about important theoretical significance and practical value. Geological disaster is forecasted by using integrated geological prediction technology immediately before tunnel excavation, and the geological disaster caused by rock deformation was early detected by use of monitoring and measurement technology. Landslide, bay mud and gushing water were predicted and detected successfully to avoid casualties and major economic loss.

Key words: tunnel informational construction, geological hazards, comprehensive geological prediction, monitoring and measurement, prediction and early-warning
