SETTLEMENT ESTIMATE EQUATION OF PILE AND ITS APPLICATION TO FOUNDATION DESIGN

Abstract

When plural kinds of piles coexist in a foundation, the pile settlement characteristic influences the foundation behavior greatly. For example, when new piles are added for the reinforcement of an existing bridge foundation supported by piles, the new pile's behavior differs from the existing pile's behavior in the stress and the settlement. It is difficult to carry out such a pile foundation design reasonably without considering the pile settlement characteristic. The settlement estimate equations were proposed that are applicable to the practical design in such cases. The proposed equations make the pile foundation design reasonable. This paper also showed the pile foundatin design method using the equations.
