Abstract
If the characteristic is standardized every pile types, it is very convenient for the design work of pile foundation. Recently, there is a tendancy that buildings are built by reusing existing foundations. The foundations of these buildings are likely made of different types of pile, therefore, it is important to know fully the settlement characteristics of the each pile in the design process. Based on such intention, curve fittings for the relationship between load and settlement of piles were carried out by using data of many pile loading tests. The most suitable curve equation was searched that represents the settlement characteristic of piles. The relation between parameters of the curve equation and the pile species was analyzed by the multiple regression analysis. At the results, an equation was obtained that represents the settlement characteristic every pile species.
