Abstract: The tunnel excavation generates soil settlement around the pipeline, and causes the pipeline to deform and suffer bending moment. The Loganathan’s formula is used for predicting the soil displacement at the pipeline level; and the equivalent model of the forces acting on the pipeline is given. A Winkler solution is used for estimating the bending moment for the pipeline affected by tunneling. A case is analyzed; and the solution is compared with an elastic continuum solution and Attwell’s solution. The results show that the method is valid.

Key words: tunneling, buried pipelines, Winkler-based model, bending moment of the pipeline
