红外探水技术在岩溶隧道施工中的应用

Infrared Acquisition Technology Applied to Karst Tunnels

以大广南高速公路长乐山隧道工程为例,阐述了红外探水技术的基本原理、特点和操作方法,以及HY-303红外探水仪在工程中的应用实践,并分析了几种干扰场影响下红外探水预报的处理方法。研究结果表明:红外探水技术针对岩溶隧道含水体的预报是十分准确的,值得在岩溶隧道施工地质预报中选用。

Basic principles of infrared acquisition technology and HY-303 infrared acquisition meters adopted in Changleshan tunnel on Daguannan expressway are described,solutions are introduced to deal with several kinds of interference fields.The practice showed that the predicted results of infrared acquisition technology were rather accurate especially for water-bearing bodies.It is worthy of utilizing this technology for tunnel geological prediction in karst district.
