This paper presents different methods for analyzing short term ground-structure interaction for segmented tunnel lining. These include an analytical solution (AS) proposed by Naggar and Hincherberger (2008), a hybrid method (geotechnical model combined with a structural model) and numerical modeling in two and three dimensions using the Finite Element Method (FEM). The analytical solution demands less time than numerical solutions, furthermore, it allows making sensibility analysis to soil parameters. However, analytical solutions are limited by their hypotheses, for instance, assuming plane strain condition. 2D numerical modeling permits obtaining approximate results in less time than the 3D modeling, assuming that the characteristics of elements used for the joints are appropriate. On the other hand, the 2D numerical and analytical analysis lead to a flexible response of segmented lining and may underestimate internal forces. Numerical modeling in 3D is the most complete option because it allows the representation of the fundamental aspects of the problem, principally coupling between contiguous rings and boundary conditions. Nevertheless, 3D analyses may require excessive computing time.
