摘　　要：准确而有效的地质超前预报工作,可为施工单位节约大量成本,加快施工进度,所以隧道施工中地质超前预报应用也越来越广泛。地质超前预报通常分为长期预报和短期预报,红外探测技术是短期地质超前预报方法中的一种,该技术多在煤矿井下用于探水和探火,最近几年来将其应用于隧道地质超前预报中进行突水预测,目前还处于尝试阶段。提出了传统探测方法存在探测点少、解译结果简单等问题,针对厦门海底隧道实际情况采用了增加探测点的方法,并以地质知识和现场地质调研为基础分析了探测前方含水断层的大致产状、位置、含水量,讨论了在现场探测中所碰到的一些问题及相应的解决办法,总结了一些现场经验和一些尚未解决的问题。研究旨在为今后红外探测技术在隧道地质超前预报中的应用提供了有意义的借鉴。In tunneling accurate and effective geological prediction can save a lot of cost for construction corporations and accelerate the construction progress,so the application of geological prediction is getting more extensive application in tunnel construction.Geological prediction is usually divided into long-term forecasting and short-term forecasting.The infrared acquisition technology is one of the short-term forecasting means,this method is usually used to predict water and fire state in coal mines,it is used to predict water gushing as one of the tunnel geological prediction methods in recent years,now it is still in the experimental stage.The problems of few probing points and simple interpretations of traditional probing method are pointed out.Increasing probing points are applied for the Xiamen sub-sea tunnel,the strikes,positions,water content of the forecasting water-bearing faults are analyzed based on geology and lots of geological surveys,the problems and corresponding solutions in the progress of probing are discussed,some experience and still existing problems are summarized.This study offers significant references for the application of the infrared acquisition technology in tunnel geological prediction in the future.
