Detection method and system for tunnel convergency and deformation

Abstract

The invention provides a detection method and system for tunnel convergency and deformation, relating to the technical field of tunnel deformation detection. The method comprises steps that each detection device takes an initial position image of each of the other detection devices fixed on the same detection section, processes the initial position image so as to acquire initial position coordinates of each detection device, then sends all initial position coordinates to an external monitor center to process so as to obtain a standard convergent parameter; the external monitor center generatesa corresponding detection instruction according to a detection demand, and sends the detection instruction to each detection device; each detection device takes a real-time position image of each ofthe other detection devices fixed on the same detection section according to the detection instruction, and processes the images to obtain real-time position coordinates of each detection device; eachdetection device sends the real-time position coordinates to the external monitor center; and the external monitor center processes according to the real-time position coordinates and standard convergent parameters so as to obtain a convergence detection result. The method effectively saves manpower cost, and improves real-time detection efficiency of tunnel convergency and deformation.

Description

technical field [0001] The invention relates to the technical field of tunnel deformation detection, in particular to a method and system for detecting tunnel convergence deformation. Background technique [0002] With the acceleration of national infrastructure construction, the demand for safety testing of large-scale infrastructure projects such as subways, railways, highway tunnels, urban river-crossing tunnels, oil pipelines, and water conservancy culverts is increasing. Tunnels will be deformed during use and operation, such as vault sinking, arch waist convergence, etc. The so-called tunnel convergence deformation refers to the deformation of the cross-sectional shape of the tunnel caused by factors such as uneven pressure outside the tunnel. The above-mentioned external pressures include the ground, surrounding building loads and soil disturbances during the operation of the tunnel, the construction of the surrounding engineering of the tunnel and the construction of...

Problems solved by technology

The resolution of this measurement is not high. At the same time, due to the small change in tunnel deformation and long observation time, the observation frequency may be once a few days or once an hour. Such manual observation makes the measurement accuracy and efficiency relatively high. Low, and nearly impossible for running tunnels
