000019039 520__ $$2eng$$aPerformance of three different types of pile foundation (single, 2x2 and large group pile foundations) then under construction thus without superstructures during the 2011 Tohoku earthquake was examined on the basis of field investigation including inclinometer and camera survey together with pseudo static pushover analysis. It was shown that: (1) all single and one 2x2 group pile foundations were vitally damaged at the bottom of a liquefied layer and displaced horizontally by up to 60 cm, whereas the other large group pile foundation survived without any damage; (2) the largest bending curvature occurred near the bottom of the liquefied layer in all the damaged pile foundations, confirming strong effects of ground displacement of the liquefied sand; and (3) the difference in pile moment capacity and pile head constraint might have differentiated the performance of the three different pile foundations during the earthquake.
