However, for long-distance buried pipelines, the biggest problem, in addition to the corrosion problem, is the earthquake. According to a large number of earthquake damage statistics, the damage of the buried pipeline in the earthquake generally occurs in a movable fracture zone. When a long-distance buried pipeline crosses a fault, the buried pipeline deforms along with the deformation of a soil body due to large dislocation of the ground of the fault area and is subjected to the action of soil body counter forces from the transverse direction and the axial direction of the pipeline, so that when the pipeline is pulled, if the tensile strain exceeds a limit value, the pipeline is damaged; buckling failure can occur when the pipe is compressed due to buckling of the shell.
