Method and system for monitoring deformation of railway infrastructure in pipe jacking construction process

The invention relates to the technical field of railway infrastructure deformation monitoring, and provides a railway infrastructure deformation monitoring method and system in the pipe jacking construction process, and the method comprises the following monitoring steps in the pipe jacking construction process: carrying out vertical and transverse deformation monitoring on a railway roadbed structure; performing vertical and transverse deformation monitoring on the railway track structure; carrying out geometric shape and position monitoring on the railway track structure; carrying out displacement monitoring on the seamless track steel rail of the railway; and the stripping of the railway switch rail and the stock rail is monitored. According to the scheme, the influence on the rail infrastructure above in the pipe-jacking construction process is considered, so that the settlement or deformation data of the railway infrastructure can be acquired in real time by monitoring the railway infrastructure in real
