� � This report aims to develop a three-dimensional effective stress analysis method in which soil properties can easily be set from the results of conventional tests.� The excess pore water pressure buildup in the saturated soil in the three-dimensional analysis is evaluated based on the extension of the cumulative damage concept in a one-dimensional case in which the liquefaction strength curve is expressed as a relation between shear stress amplitude and number of cycles. The proposed method
more » ... The proposed method is validated by simulating three dimensional blast-induced shaking experiment conducted on a large soil-pile-structure models. It is important to notice that three directional input motions are critically important, since one directional input motion could not obtain good agreement with the experiment. � �
