The invention discloses a tunnel collapse rockfall full-automatic real-time monitoring-early warning system and method. The tunnel collapse rockfall full-automatic real-time monitoring-early warning system comprises an information acquisition unit, an information transmission unit, an information analysis unit and an early warning unit, wherein the information acquisition unit acquires image and video information of each fault surface inside a tunnel, determines an optimal observation position, performs compensation and leveling on the acquired information and transmits the processed information to the information analysis unit through the information transmission unit, and the information analysis unit analyzes the monitored information, set an early warning level for different types of collapse and forecasts according to the early warning level. The system and method disclosed by the invention solve problems in tunnel monitoring and measurement that that manual measurement is poor in timeliness and a safety evaluation system is not standard.
Description
technical field [0001] The invention relates to a fully automatic real-time monitoring-early warning system and method for rockfall in tunnels. Background technique [0002] With the advancement of the development strategy, the number of tunnels in our country is increasing. During tunnel construction, landslide is one of the common failure modes of surrounding rock instability. Due to its complex nonlinear and sudden characteristics, it is difficult to predict, and has become an extremely prominent safety hazard in tunnel construction. Once a landslide accident occurs, it will cause construction difficulties, mechanical damage, delays in the construction period, and even casualties. Such tunnel engineering accidents are not uncommon. [0003] Monitoring and measurement is an important part of tunnel construction. From the construction point of view, the biggest role of surrounding rock measurement is to analyze and judge according to changes in deformation, deformation ra...
