Abstract

This paper presents the effect of tunneling on bridge pile foundation being operated using three-dimensional numerical modeling. Also the parametric study on the depth of tunnel of which the diameter was 10 m was carried out in order to evaluate the behaviors of pile foundation due to the tunnel excavation. This paper expresses the changes of vertical and horizontal displacement, movement of soil and stress of the pile. Based on the results obtained from the numerical analysis some insights into the changes of pile foundation behaviors due to variations of tunneling location were mentioned and discussed.
