ABSTRACT
Iran is a vast country with 1.6m square kilometer area and more than 70 million inhabitants.
Tehran, the capital of Iran, together with its satellite townships is home to more than one sixth
of the country’s population which make over 13 million mostly motorized daily journeys. This
work is based on geotechnical investigation a metro station case study in Tehran. The access
gallery and tunnel inter-section problems is very sensitive and dangerous in critical zones of the
tunnel lining has been discussed in this paper. One of the objectives of this paper is defining
the seismic modeling of tunnel. Specifying the differences between the two PLAXIS and FLAC
seismic modeling is another aim of this paper.
Keywords: Geotechnical investigation seismic modeling, FEM, FDM, tunnel, Tehran, Iran.
