Abstract

The invention discloses an immersed tube underwater deformation monitoring method, which comprises a transverse deformation measurement step and a longitudinal deformation measurement step. The transverse deformation measurement step comprises a transverse feature point calibration substep, a distance calibration substep and a transverse deformation quantity calculation substep; the longitudinal deformation measurement step comprises a longitudinal detection point calibration substep, a range finder installation substep, an initial distance measurement substep, a real-time distance measurement substep and a longitudinal deformation quantity calculation substep. The technical problem that the immersed tube deformation cannot be accurately obtained in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of submarine immersed tubes, in particular to an underwater deformation monitoring method of immersed tubes. Background technique [0002] The steel shell concrete immersed tube manufacturing method is the first large-scale application in the world. At present, the prefabrication of large steel shell tube sections adopts the dry dock method or floating pouring. However, in the prior art, there is a lack of monitoring methods for the longitudinal and transverse deformation of the steel shell immersed tube during underwater construction, resulting in the inability to accurately obtain the deformation of the immersed tube. Contents of the invention [0003] The object of the present invention is to provide a kind of immersed tube underwater deformation monitoring method, to solve the technical problem in the above-mentioned prior art that the deformation of the immersed tube cannot be accurately obtained. ...
