Abstract

There is a lot of research on the effects of earthquake loading on the forces and displacements of underground structures. Some researchers have investigated the influence of loose sand lenses that form due to geological processes in the saturation areas. However, an assessment of the influence of the sand lens dimensions on underground structures such as tunnels has rarely been assessed. Thus, the attempt of this paper is an assessment of the effects of width variation of liquefiable sand lens on surface settlement due to shallow tunneling. In this research, FLAC-3D software has been used to model the pore pressure changes and surface settlement during the liquefaction of the sand lens. According to the results, an increase in the sand lens width tends to have a direct correlation to the increase in surface settlement.
