In this study, the behavior of the underground structures undergone to seismic earthquake
loads was studied in closed differential equations and in numerical methods, and the
comparative results were presented. A circular tunnel liner was considered in soft and
weathered rock materials and in soft soil ground media and analyses were executed. The
results of the analyses were found compatible, and the results of the numerical analyses for
the non-linear behavior of the materials undergone to earthquake loads, under above
mentioned surrounding ground conditions, were found more consistent compared with the
solutions based on elastic material behavior such as Simplified Deformation Analysis,
Free Field Shear Strain Approach, Simplified Frame Method and Pseudo-static Analysis.
Key words: Tunnel, seismic analysis, numerical analysis, FE analysis, earthquake analysis
