Three dimensional analysis on lateral flow of liquefied ground and its mitigation by sheet pile walls

Abstract

Since the design policy of countermeasures to liquefaction is currently prevention of liquefaction, conventional liquefaction analysis aims to predict the possibility of liquefaction at a target site. However, quantitative prediction of ground flow by liquefaction has been studied for new design policy that allows the deformation of liquefied ground if it is not critical. This paper presents a method for prediction of the ground deformation related liquefaction by viscous fluid model. Furthermore, the mitigation effect of a sheet pile wall is assessed by modeling a sheet pile wall as an elastic beam.
