Abstract
Inclinometer survey and television observation are conducted for piles of a building that experienced severe tilt due to liquefaction-induced lateral spreading during the 1995 Hyogoken-Nambu earthquake. The result of the field tests together with a preliminary analysis has shown that (1) there is a significant difference in the failure and deformation patterns of piles along the line perpendicular to the shoreline, and (2) this difference could have been induced by the change in the lateral ground displacements along the line.
