등가변형을 이용한 테이퍼 말뚝의 지지력 산정 = Estimation of Axial Load Capacity for Tapered Piles Using Equivalent Transformation

다국어 초록 (Multilingual Abstract)

In this study, a method using equivalent transformation for estimation of the axial load capacity of tapered piles is proposed. While preexistent methods for estimating the axial load capacity of tapered piles have been based on the effect of soil state and taper angle, a new design method is proposed considering cone resistance and equivalent transformation in sand. Through tapered pile simplified by using equivalent transformation, a new method for quick and easy estimation of the axial load capacity of tapered pile is proposed for practical use. In order to verify the proposed method, calibration chamber test and field test were conducted. In calibration chamber test, comparison of estimated axial load capacity with measured one showed that the standard deviation and COV (Coefficient Of Variation) of estimated is 0.05～0.121, 0.04～0.05 respectively. For field test, axial load capacity by proposed method shows 2.5% under-estimation in comparison with measured value. As a result, it is found that proposed method produces satisfactory predictions for tapered piles.
