Problems solved by technology

[0003] The traditional method of monitoring the deformation of the tunnel section mainly monitors by installing a joint gauge in the annular seam of the tunnel segment. This method can only measure the deformation at a single point, and because a single joint gauge is expensive, it cannot Realize the large-area installation of joint gauges, making it difficult to reflect the overall deformation of the tunnel section

Abstract

The embodiment of the invention relates to a tunnel section deformation measurement method and device and a storage medium. The method comprises the steps that the deformation of a plurality of preset measurement points of a tunnel section in the longitudinal direction of a tunnel is obtained; fitting the deformed tunnel section according to the deformation amount of each preset measurement point and the initial position coordinate of each preset measurement point on the tunnel section to obtain a fitting plane; and according to the fitting plane, determining the deformation amount of each to-be-measured point of the tunnel section in the longitudinal direction of the tunnel, so that deformation measurement of any measurement point on the tunnel section can be realized without installing a large number of measurement devices in the tunnel segment circular seam, and thus the overall deformation condition of the tunnel section can be conveniently obtained.

Description

technical field [0001] The present disclosure relates to the technical field of tunnel engineering, in particular to a method, device and storage medium for measuring deformation of a tunnel section. Background technique [0002] The shield tunnel is formed by splicing a series of segment rings. During the operation of the tunnel, affected by the ground, surrounding loads, engineering construction, etc., the segment structure will be deformed, which will affect the operational safety of the tunnel. In order to ensure the safety of the tunnel structure, the safety monitoring of the tunnel structure needs to be carried out regularly or irregularly, and the deformation monitoring of the tunnel section is a very critical monitoring factor in the safety monitoring of the tunnel structure. [0003] The traditional method of monitoring the deformation of the tunnel section mainly monitors by installing a joint gauge in the annular seam of the tunnel segment. This method can only me...
