Abstract
In this study, the effect of aspect ratio and soil strength on the skin friction for barrette pile was evaluated using numerical analysis. The back analysis was conducted to obtain the friction coefficient between pile and soil using the experimental results of the static pile load test for the barrette pile installed at OOsite in Busan. A total of 36 simulations for the static pile load test were also conducted with respect to various aspect ratios and soil strengths. It was found that the skin friction increases as the aspect ratio increases and the change in increasing rate was remarkable near the ultimate skin friction. In addition, the effect of aspect ratio on the skin friction was investigated when the strength of soil at pile tip was varied.
