红外探水在厦门海底隧道中的应用

在厦门海底隧道施工中采用红外探测仪进行探水短期预报。介绍了红外探水技术的基本原理和布点方法,通过实例分析了分部红外探测得到的红外辐射场强值和绘出的红外探测曲线,得出探测结论,并和实际情况进行验证,说明探水效果良好,为隧道顺利施工提供科学依据。结合应用情况,提出了当前红外探水技术发展中亟待解决的问题。

The Application of Infrared Water Detectors to Xiamen Seabed Tunnel

In the construction of the Xiamen Seabed Tunnel,we use infrared detectors for short-term water detection.The basic principles for and stationing methods of infrared water detection are presented in the paper.With the project as a practical example,part of the detection curves and infrared radiation field intensity values obtained from infrared detection in the cross-section are analyzed in the paper.Finally,the survey results are checked and proved in practice.The effects of infrared detection are found satisfactory and able to provide a scientific basis for tunnel construction.On the basis of practical application,problems which badly need to be solved in the development of infrared water detection technology are also put forward in the paper.
