Abstract
A jacket-type steel-pile foundation has a feature that it can reduce the load acting on the piles drastically because the foundation and the superstructure are connected continuously by the jacket that is much lighter than a conventional top-heavy foundation. Moreover, if inclined piles are properly used as a pile foundation, it is possible to increase efficiently the lateral resistance and the rigidity of the foundation. In this paper, the lateral resistance and the failure mechanism of a group-pile foundation with inclined piles by centrifuge model tests, the influence of the pile spacing and the inclined angle of the piles on the lateral resistance were analyzed by 3-D finite element analysis.
