PROBLEM TO BE SOLVED: To provide a behavior estimation method of a fault traversal underground buried pipeline capable of simply obtaining a degree of precision without using a large scale simulation device.SOLUTION: A behavior estimation method of a fault traversal underground buried pipeline includes: a level of the displacement influence estimation step, which is executed when a bending angle of a specific aseismatic joint constituting the pipeline by the fault displacement exceeds a reference allowable bending angle α, of obtaining a level of the displacement influence k showing a ratio of a shift amount δj of the specific aseismatic joint for a fault displacement excess amount δ by an estimation formula using coefficients P1i and P2i of each category for at least two target amounts P1 and P2 determined based on the quantification theory type 1; and an aseismatic joint behavior estimation step of calculating a bending angle θ of the aseismatic joint with respect to an assumed fault displacement amount on the basis of the displacement influence k and estimating the behavior of the aseismatic joint on the basis of a calculated bending angle θ.SELECTED DRAWING: Figure 6
