Abstract
The pile tip levels, which are the foundation levels of piled structures, are correlated with the ground surface levels from the geological point of view. We had proposed before the estimation method which is based on the cokriging procedure and had produced excellent results. This paper presents the new estimation method of pile tip levels taking account of not only the ground surface levels but also the elastic wave exploration data. For the purpose of preventing from increasing of model parameters, the ground surface levels are treated as the trend component. In this paper, the proposed method was verified using the numerical data and applied to the actual data.
