Abstract

In views of the limitations of the existing methods for calculating the pile foundation capacity, a back analysis approach of the $m$-value is introduced. In order to consider the sensitivity of pile behavior to the $m$-value, the relationships between the applied horizontal loads at pile head and the corresponding $m$-value along with the pile stiffness changes are studied. Based on statistics data from the extensive in-situ tests, the back analysis results suggest an exponential expression for the $m$-value in various soil conditions and horizontal displacements at pile head. This method is capable of providing an accurate $m$-value in calculating the pile responses under lateral loads.
