Abstract

The invention discloses a tunnel deformation monitoring system and method. The system comprises an arc rack, wherein the arc rack is arranged on a maintenance vehicle, an arc surface of the arc rack is perpendicular to a travelling direction of the maintenance vehicle or a certain non-zero angle is shown between the arc surface of the arc rack and the travelling direction of the maintenance vehicle, a plurality of image sensors, a plurality of light supplement lamps, a plurality of measurement arc racks and a tunnel lining distance deformation detection module are arranged on the arc rack, andthe system also comprises a gesture sensing module, an image acquisition module, a control system and a server. By the system, a panoramic image of a tunnel and could data of a topographic range point can be acquired, a true three-dimensional image of the tunnel is constructed according to the image data and the cloud data of the distance point, the construction of a tunnel convergence map is achieved in a non-contact way and is compared with a tunnel standard convergence map or a previous measurement result to achieve tunnel deformation detection, and visual image observation of a deformation abnormal point is achieved; and an error caused by vibration, turning, acceleration and deceleration during travelling of the maintenance vehicle is compensated by the gesture sensing module, and the accuracy of the measurement result is improved.

Description

technical field [0001] The invention relates to the field of tunnel detection, in particular to a tunnel deformation monitoring system and method. Background technique [0002] During the construction and operation of the subway tunnel, due to the ground, the surrounding building load and soil disturbance, the construction of the surrounding engineering of the tunnel and the construction of the tunnel engineering structure, the vibration of the subway train, etc., the comprehensive impact on the tunnel will cause the deformation of the tunnel. For the safety during the construction and operation of the subway, relevant units will regularly monitor the deformation of the subway tunnel. The deformation monitoring of the tunnel is of great significance to the safety of the tunnel construction and operation stages. [0003] At present, the traditional detection methods mainly rely on special measuring instruments (total station, profiler, convergence meter, etc.) and the method ...
