摘要

A practical method to estimate the structural strains of buried pipelines under lateral spreading in the liquefied ground is proposed. Two different patterns of ground deformations at slope and revetment are selected as the typical lateral spreading modes. The shell/beam hybrid model is used to analyse the inelastic behavior of buried pipes, using the FEM code of ABAQUS. For the practical formulation conforming to those FEM results, the plastic limit analysis method is adopted to deal with the plastic behaviors of pipeline systems. Finally, a simplified design formula is deduced to evaluate the deflection angle of the bend corner in the pipeline system, from which the structural strain can be estimated with the relationship between the maximum structural strain and deflection angle of the bend.
