ABSTRACT
The object of this study is to explore the reasons resulting in the failure of pile foundations built on the soft reclaimed ground due to the 1995 Hyogo-ken Nambu Earthquake. Based on the case investigation results, at first, numerical analyses have been perfomed to examine the dynamic bahavior of the soil-pile-structure system during earthquake shaking. Then, the seismic capacity of piles was investigated when the permanent ground displacements occurred due to the softening of liquefied soils. The following main conclusions have been drawn. 1) The collapse of middle parts of piles may be caused by the lateral forces due to soil liquefaction; 2) The damage of the pile tips may be attributed to the permanent ground displacements due to post-liquefaction.(AU)
