  • Earthquake can give rise to settlement of ground, soil liquification and ground crack, which will destroy the buried pipelines. To ensure a safe operation for pipeline, the study on the earthquake must be carried out to keep the buried pipeline withstand the earthquake force with a certain intensity. The effect of seismic ground crack on buried pipeline is analyzed, and the finite element equations applied on the buried pipeline under the effect of seismic ground crack have been obtained by the principle of minimum potential energy. These equations can be used to calculate the displacement, internal force and stress of the buried pipeline under the effect of seismic ground crack, and some calculating cases are introduced.
