【摘要】 突水、涌泥是隧道工程的主要地质问题,是隧道施工中的安全隐患。隧道在岩溶地段施工时,为有效地防止隧道在施工过程中发生突水、涌泥,应进行隧道超前地质预报。红外探测技术是一种预测预报技术,它能够探测隐蔽的水源。介绍了红外探测技术的基本原理,并采用HY-303型防爆红外探测仪对龙潭特长隧道进行了超前探水预报。通过分析探测结果表明,该仪器能够在岩溶地区隧道工程的超前预报中发挥作用,红外探测技术值得在复杂地质条件下的隧道工程中推广。更多还原

【Abstract】 Water rush and mud rush are two major geological problems in tunnel engineering,which can lead to hidden troubles during tunnel construction.To prevent the emergence of water rush and mud rush during the construction of tunnels in karst areas,advanced geological prediction should be carried out.Infrared detection,one of the forecast techniques,can detect the hidden water resource in front of the tunnel face.In this paper,the basic principles of model HY-303 infrared detection meter are described in detail.And it is applied to predict hidden water resource in Longtan super long tunnel.The application results show that infrared detection technique is feasible in water rush forecast in karst areas and will have a good application opportunity in tunnel engineering under complex geological conditions.更多还原
