Pile behavior due to tunnel excavation

Abstract

Tunnel excavations in soils can have a significant effect on nearby piles. The tunneling processes generate stresses and forces, which are transferred through the surrounding soil of the tunnel to the adjacent piles. It is important to determine the effects of tunneling to prevent damage to the piles and the structures that are carried by those piles. In this article, the behavior of piles under tunneling processes is studied. The soil is modeled using Mohr-Coulomb model, while the piles are modeled as a linear elastic material. Furthermore, the tunnel shape effects on pile behavior are studied, and its cases are investigated. The results show that by using circular tunnels, they have the minimum effects on adjacent piles regarding the bending moment, lateral and vertical displacements, and Von-Mises stresses compared with using square or elliptical tunnels.
