Embodiment 1
[0040] This embodiment provides a "landslide-tunnel" system deformation identification and linkage monitoring method, including: a "landslide-tunnel" system deformation identification method, a "landslide-tunnel" system deformation monitoring method and a monitoring result feedback method. The deformation identification method of the "landslide-tunnel" system includes a landslide deformation identification method and a tunnel deformation identification method, wherein the landslide deformation identification method adopts Interferometric Synthetic Aperture Radar (InSAR) technology to initially determine the plane range of the landslide . Specifically, taking advantage of the unique advantages of InSAR technology to trace the historical deformation data within a certain time range before the landslide was discovered, analyze the evolution process of the landslide through time-series InSAR data, combined with meteorological and hydrogeological data in the landslide area, Prelimi...

The invention discloses a method for identification and linkage monitoring of the deformation of the landslide-tunnel system. Firstly, the deformation of the landslide-tunnel system is comprehensively identified by synthetic aperture radar interferometry technology and geological radar, and the landslide-tunnel system is detected by the monitoring data of the inclinometer tube. Carry out classification, simulate the deformation characteristics of different systems through finite element numerical simulation, and propose corresponding monitoring indicators and monitoring methods. Linkage monitoring method. The technical scheme provided by the invention considers both the landslide and the tunnel as a whole, which saves the monitoring cost compared with the separate monitoring of the landslide and the tunnel, improves the economy of monitoring, and improves the efficiency and reliability of the identification and monitoring method.
Description
technical field [0001] The invention relates to the technical field of geological disaster deformation monitoring, in particular to a method for identification and linkage monitoring of landslide-tunnel system deformation. Background technique [0002] About 70% of China's land area is mountainous terrain. In the construction of trunk lines passing through mountainous areas, a large number of tunnels need to be built. Usually, if it is found that there is a possibility of landslide on the mountainous slope through which the tunnel passes, technical measures such as changing the route to avoid it according to the actual situation, passing the deep tunnel under the slide bed, or repairing the landslide first and then building the tunnel will be adopted to solve the problem. It is impossible to construct the tunnel directly in the landslide body. However, the hydrogeological environment of the rock and soil where the tunnel is located is constantly changing. The rock mass str...
