深埋长大隧道工程地质条件复杂多变,盲目施工易造成突水、突泥和塌方等安全事故。对隧道掌子面前方一定范围内的地质情况进行超前探测和预测预报是保证隧道施工安全的关键技术。在连霍高速将军沟隧道施工中,引进TSP203隧道地质超前预报系统、红外线测水仪等先进仪器进行多途径超前地质预报,可以有效的提高对不良地质体的预报效果,通过预报结果与实际揭露的对比分析,其预测精度达到95%以上,有效地指导了隧道的安全施工,可为同类工程提供技术资料和经验借鉴。
The geological conditions of deep and long tunnels are complex and changeable, blind construction can easily lead to water inrush, mud and landslides and other safety accidents. Probing and predicting the geological conditions within a certain range in front of the tunnel face is the key technology to ensure the construction safety of the tunnel. In Lianhugao high-speed general ditch tunnel construction, the introduction of TSP203 tunnel geological advanced forecasting system, infrared water meter and other advanced equipment for multi-channel advanced geological forecasting, can effectively improve the prediction of bad geological body, through the forecast results and the actual disclosure , The prediction accuracy reaches more than 95%, effectively guiding the safe construction of the tunnel and providing technical information and experience for similar projects.
