EVALUATION OF SOIL LIQUEFACTION POTENTIALS IN PARTIALLY DRAINED CONDITIONS

概要

論文の詳細を見る
A liquefaction test method has been developed to evaluate liquefaction resistances under partially drained conditions. Both the influence of drainage conditions and the effect of cyclic frequencies on liquefaction are evaluated by conducting several series of liquefaction tests under different conditions of drainage including the undrained condition. It has been found that the strength increase due to partial drainage can be well represented by the relative density and the coefficient of drainage effect defined by α^^-=k/(fL), in which k is the permeability ; f is the frequency of cyclic loading ; and L is the length of drainage path. An evaluation method of liquefaction potentials in partially drained conditions has been proposed with an application to a case study.
