铁路隧道的检查几乎都是在夜间列车停运的时间内进行,所采取的方法是用榔头敲击边墙、拱顶、听声音判断;或者用机械钻孔,用肉眼观察。这些方法耗时费力,因此,本文着眼于不使隧道受直接的损伤,并能连续地进行调查的方法,试图把调查埋设物所用的电磁波法和调查边坡混凝土的背面状况等的热红外线图像法用于隧道检查,探讨其适用性。这是隧道检查的一种新尝试,可供参考。 Almost all of the railway tunnel inspections were carried out during the night when the train was out of service. The method was to use a hammer to tap the side wall, the vault and listen to the sound, or to drill the hole with a naked eye. These methods are time-consuming and labor-intensive. Therefore, in this paper, aiming at a method of continuous investigation without affecting the tunnel directly, an attempt is made to analyze a thermal infrared image such as an electromagnetic wave method for surveying embankment and a survey for the condition of the backside of a concrete slope Method for tunnel inspection to explore its applicability. This is a new attempt at tunnel inspection for reference.
