Abstract
A series of shaking table tests were carried out to observe the behavior of a single pile subjected to laterally spreading liquefied ground. The pile was modeled as buried cylinder that corresponds to a sectional model of a prototype pile at a certain depth in the subsoil. The effects of ground shaking, relative density, loading rate and pile displacement to the lateral resistance of the pile were studied. It was found out that there is a small variation in the excess pore water pressure and lateral resistance of pile during ground shaking presumably because of the effects of dilatancy was prevented to develop. After ground shaking, there is an increase in effective stress with the movement of the pile as manifested by the sudden decrease in the excess pore water pressure, consequently an increase in rigidity and this also lead to the increase in the lateral resistance of the pile. Empirical equations for computing the lateral resistance of a pile subjected to lateral spreading as a function of relative density, loading rate and pile displacement were derived for “shaking” and “post-shaking” events.
