The invention relates to the field of underground space engineering, and discloses a pipeline deformation monitoring method and device, and the method comprises the steps: building a relation between the height of a soil body balance unit and the vertical stress borne by the soil body balance unit based on the preset soil body balance unit in a soil arch region caused by the lateral movement of a pipeline, and obtaining a first model; based on the first model, introducing a boundary condition, and establishing a relational expression between the soil arch height and a constant to obtain a second model; based on the second model, introducing a soil body compression amount, and predicting a soil arch height; and judging the deformation condition of the pipeline based on the height of the soil arch. The buried pipeline deformation monitoring device can achieve the effects of improving the accuracy of buried pipeline deformation monitoring and reducing the test time and the manpower and material resource cost. 本申
