Abstract
This paper shows the effects of the degree of consolidation of the soft clay layer on the strong motion response. Seismic behavior of the Kobe artificial islands during the 1995 Hyogo-ken Nambu earthquake is studied by using centrifuge shaking table test. At the earthquake, it is known that the liquefaction damage of artificial island was different from each other. Authors consider the reason why is due to the degree of consolidation of clay layer underlying the reclaimed ground. The model grounds used for the centrifuge test are made by the clay and fill material sampled from Kobe artificial island, and each clay layer of models is consolidated as the same degree as the sites. First, from the viewpoint of the reproducibility of in-situ behavior, the seismic response and the ground settlement are compared with observation data. Next, we compare the seismic response of the test results of the different degree of consolidation. It is found that the degree of consolidation and the shear strength of the clay layer significantly affect the ground behavior. The large damage is not always come to being on the ground with soft clay layer.
