Influence of Shield Tunneling on a Nearby Buried Pipeline
The influence of shield tunneling on a nearby buried pipeline is studied by using the analytical method. Equations of displacements, rotations, bending moments, and shearing forces of a buried pipeline are set up respectively on the base of the theory of Winkler’s beam on elastic foundation. It shows the maximum settlement of the buried pipeline occurs in its middle span. Both the maximum bending moment and the shearing force of a buried pipeline take place at its two ends. The diffusion angle of the subgrade and the buried depth of the buried pipeline play an important role in the behavior of the buried pipeline.
