Abstract
The liquefaction behavior of the reclaimed land of Kobe artificial island was examined using on-line test. The array observation site in the Kobe Port Island at Hyogo-ken Nanbu Earthquake in 1995 was modeled as the four lumped mass system. The top layer above water level and the forth layer of alluvium clay layer are modeled by the hyperbolic model. The second and third layers in the reclaimed layer are directly modeled by the elementary test. As the result, it was proven that the liquefaction of the reclaimed land is significantly affected by the shear strength of the alluvium clay layer. The results obtained from on-line test showed good agreements with the array record.
