Automatic monitoring and early warning method and system for tunnel section deformation

Abstract

The invention provides an automatic monitoring and early warning method and system for tunnel section deformation. The method comprises the steps of collecting surrounding rock deformation data in tunnel monitoring measurement parameters through a laser scanner; acquiring selective measurement parameters in the tunnel monitoring measurement parameters through a comprehensive tester; analyzing thesurrounding rock deformation data and the selective measurement parameters, and judging whether a measured value in the surrounding rock deformation data at the current moment is greater than a firstthreshold value or not and whether a measured value in the selective measurement parameters at the current moment is greater than a second threshold value or not; and judging whether a judgment resulttriggers an early warning condition or not, and performing early warning after the early warning condition is triggered. All-weather and 24-hour automatic monitoring and early warning are realized, through real-time acquisition, real-time analysis and real-time early warning technologies of tunnel intelligent monitoring data, response time can be won in advance for occurrence of tunnel geologicaldisasters and engineering treatment, disaster accident loss is reduced to the maximum extent, safety of construction tunnels and operation tunnels is guaranteed, and the method has important engineering application value and huge social and economic significance.

Description

technical field [0001] The invention relates to the technical field of tunnel monitoring, in particular to an automatic monitoring and early warning method and system for tunnel section deformation. Background technique [0002] As a control project and concealed project of traffic lines, tunnels are mostly constructed in areas with large undulating mountainous terrain. Usually, the engineering geological and hydrogeological conditions of the site selection are complex and changeable, and the adverse geological conditions encountered during construction and operation There are more and more problems. Sudden accidents caused by unfavorable geological disasters in tunnels under construction and in operation have become a safety hazard in the engineering field, causing great economic losses and adverse social impacts. Therefore, it is necessary to monitor and measure the tunnel in real time to understand the stress state and stress distribution of the tunnel support structure ...

Problems solved by technology

However, the traditional manual monitoring method has low on-site measurement frequency and cumbersome operation, which cannot realize all-weather monitoring and real-time discrimination and early warning, especially cannot meet the monitoring frequency requirements of soft rock large deformation tunnels
