Study on Buried Pipeline Floatation Response Induced by Soil Liquefaction

Abstract:

On the basis of Virtual Work, in this paper, the formulae are deduced for the floatation response of buried pipeline duo to the soil liquefaction. A beam model based on the theory of beam on elastic foundation is used for the pipeline buried in non-liquefied and liquefied area, considering the effects of nonlinear soil constraint and the initial deformation, the length of liquefied area, and the axial force acting on the pipeline. The study of floatation response of buried pipeline are conducted using the nonlinear increment element method, some results are given.
