Abstract
<p>When we conduct the prediction and judgement of liquefaction, the liquefaction properties of soils are evaluated by means of undrained cyclic shear test using in-situ soil specimens. It is considered that there are uncertainties in the liquefaction strength curve obtained because of inhomogeneous of in-situ ground, sampling disturbance and failure mode of elementary test. In this paper, the cause of deviatoric variation in the liquefaction resistance of soils is analyzed based on the data of in-situ specimen collected by Public Works Research Institute after the 2011 off the pacific coast of Tohoku earthquake. As the result, the authors clarified the tendency of the cause of variation included in the liquefaction resistance curves, and showed the superiority of evaluating the degree of liquefaction from the view point of energy.</p>
