ESTIMATION ABOUT LATERAL RESISTANCE OF PILE FOUNDATION ARRANGED SHORT PILES BETWEEN BEARING PILES

Abstract

Pile foundation arranged short piles tend to reduce the shearing force and bending moment of bearing piles by short piles. The authors carried out Static FEM about the steel pipe pile foundation embedded in elastic ground. It turned out that lateral effect of pile group about pile foundation arranged short piles can be denoted by a past estimation method by taking the influence of short piles into consideration. Moreover, comparison of dynamic centrifuge tests and static analysis which imitated these tests showed that estimation method taking the influence of short piles was appropriate in general.
