Abstract
For the purpose of developing the design method for pile foundation subjected to the liquefaction-induced lateral flow, the authors have conducted a series of both small and large scale tests as follows: first, model piles installed into model ground formed inside shear container mounted on shaking table was vibrated to be liquefied; then, the shear container was sheared by external force while vibration being applied. Based on the test results, the formula of evaluating the maximum forces applied to a single pile through non liquefied and liquefied layers have been proposed as a function of the pile layout. Moreover, the coefficient of subgrade reaction and compressive strain of layers have been clarified.
