对于隧道施工,超前地质预报是非常重要的环节,尤其在岩溶富水地段,探测水的存在与分布不仅关系到隧道施工的效率、工期等,更会直接关系到人身安全。针对红外探水的基本原理以及特点做了简单地说明,并对本工程中运用的HY-304红外探水仪加以介绍说明。然后针对本次红外探测的成果,通过与现场开挖揭露的情况进行了对比已达到验证预报的结果。结论是:对于岩溶富水区隧道中含水体,红外探水技术预报准确度较高,适合用于岩溶富水地质下的隧道开挖面前方地下水的超前探测预报。
For tunnel construction, advanced geological prediction is a very important part, especially in the karst water-rich areas, the existence and distribution of the detected water not only relate to the tunnel construction efficiency and construction period, but also directly relate to personal safety. Infrared water for the basic principles and characteristics of a simple description, and the project used HY-304 infrared detector to introduce water. Then, according to the results of this infrared detection, the results of verification and prediction have been reached by comparison with the situations exposed in the field excavation. The conclusion is that for the water body in the karst water-rich tunnel, the accuracy of infrared water exploration technology is high, which is suitable for the prediction and forecast of groundwater in front of the tunnel excavation face under karst water-rich geological conditions.
