In an effort to predict whether or not a sandy alluvium will develop liquefaction during earthquakes, measurements were made of the increase in pore pressure which is caused by pile driving. Several holes were drilled near the place at which a pile was to be driven, and piezometers and accelerometers were embedded down the holes. The pile was driven by a vertically acting vibrator and simultaneous measurements were made of pore pressures and accelerations. The place chosen for the test was a lowlying alluvium flood plain where likelihood of liquefaction in future earthquakes was of concern in connection with the foundation design of a long highway bridge. The response of pore pressure enhancement at this site was compared to the results of similar tests on other sites which had been performed under almost identical conditions.
