摩擦群杭基礎の鉛直載荷実験および有限要素法解析による支持力機構の検討

Abstract

The bearing capacity and the settlement of pile group foundation can be estimated on the assumption that the piles and surrounded ground are one homogeneous ground. Vertical loading tests of model friction pile group were carried out. The tendencies of resistance at the bottom of the footing, the frictional resistance and the pile tip resistance caused by decrease in pile spacing were confirmed by the tests. The bearing mechanism of the pile group was examined by three-dimensional finite element analyses. The hardening of the soil at the bottom of pile group could be simulated.
