A method and system for detecting tunnel convergence deformation

Abstract

The invention provides a method and system for detecting tunnel convergence deformation, which relates to the technical field of tunnel deformation detection, including: each detection device captures the initial position images of other detection devices fixed on the same detection section, and performs processing to obtain the initial position images of each detection device position coordinates, and then send each initial position coordinates to the external monitoring center for processing to obtain standard convergence parameters; the external monitoring center generates corresponding detection instructions according to the detection requirements and sends them to each detection device; Detect the real-time position images of other detection devices on the section, and process them to obtain the real-time position coordinates of each detection device; each detection device sends the real-time position coordinates to the external monitoring center; Process the results of the convergence check. The invention effectively saves labor costs and improves the real-time detection efficiency of tunnel convergence 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
