| Abstract | The mechanism of the damage to gravity type quay walls caused by the
liquefaction of backfill ground during eatthquake is investigated, regarding the vibration
properties of caisson and backfill ground, and their interaction. A series of model shaking
table tests under gravitational and centrifugal forces were conducted by Kohama,
focusing on the occurrence of the liquefaction in the backfill ground. The fluctuating
earth pressure on the caisson is quite different in magnitude and phase angle difference
with inertial force, whether liquefaction of backfill occurs or not. From the careful
examination of Kohama's investigation in this study, the fluctuating earth pressure in the
process of liquefaction showed that the interaction between caisson and backfill controls
the fluctuating earth pressure changes as a function of natural frequency of backfill with
respect to that of the caisson, which reduced due to the softening of backfill induced by
the liquefaction. This feature is demonstrated by the mass-spring-dashpot model
suggested and by finite element analysis conducted by the author. Based on the results of
Finite Element Method (FEM), a formula is presented to evaluate the cyclic earth
pressure as a function of vibration properties of caisson and backfill. |
