技术领域technical field
本发明属于隧道工程安全监测技术领域，具体涉及一种隧道变形监测光纤测试方法及系统。The invention belongs to the technical field of tunnel engineering safety monitoring, and in particular relates to a tunnel deformation monitoring optical fiber testing method and system.
背景技术Background technique
隧道作为现在基建中地下建筑工程，根据使用用途的不同，分为交通隧道、水工隧道、市政隧道、矿山隧道等。As an underground construction project in the current infrastructure, tunnels are divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels according to different uses.
隧道在开挖后，由于初始地应力场的应力释放，其结果会引发围岩周围受到各种形态的变形，如拱顶下沉、两侧围岩挤入、底部鼓起以及掌子面挤出等，而变形的后果极易导致围岩的松弛，当围岩的变形或松弛超过一定范围时，就会造成崩塌或不稳定等情况的产生。After the excavation of the tunnel, due to the stress release of the initial geostress field, the surrounding rock will be deformed in various forms, such as the sinking of the vault, the intrusion of the surrounding rock on both sides, the bulging of the bottom, and the extrusion of the tunnel face. However, the consequences of deformation can easily lead to the relaxation of the surrounding rock. When the deformation or relaxation of the surrounding rock exceeds a certain range, it will cause collapse or instability.
为了保障施工安全，对于隧道施工过程中，需要在施工过程中实时检测隧道的变形情况，甚至围岩周围的位置变化、水量渗水变化、水压变化等众多的数据需要及时采集，现在大多数数据虽然采用的都是数字化监测设备进行检测，但是对于不同数据缺乏及时分析能力，例如，在围岩位置变化可控范围内，却出现较大的水量渗水发生，也会引发不必要的围岩形变危险，需要及时处理。目前的监测手段较为单一，不能从多个数据去检测识别隧道的具体变形情况In order to ensure construction safety, during the construction of the tunnel, it is necessary to detect the deformation of the tunnel in real time during the construction process, and even the position change around the surrounding rock, the change of water seepage, the change of water pressure and many other data need to be collected in time. Most of the data now Although all digital monitoring equipment is used for detection, there is a lack of timely analysis capabilities for different data. For example, within the controllable range of changes in the surrounding rock position, a large amount of water seepage occurs, which will also cause unnecessary deformation of the surrounding rock Dangerous, need to be dealt with promptly. The current monitoring method is relatively single, and it is impossible to detect and identify the specific deformation of the tunnel from multiple data
