The results of parametric analysis on influence of discontinuities orientation on the response of rock mass during driving an underground structure in the direction of discontinuity planes are presented in the contribution. Three typical alternatives were considered: the underground structure in rock mass with one-sided dip of discontinuities, the underground structure situated in synclinal bend and the underground structure situated in anticlinal bend. In all three cases, the variability of discontinuities dip angle in the range of 0 - 90 o was considered. Mathematical models were used for the analysis by Finite Element Method using software Plaxis. Mathematical models were planar - plane strain. Rock Jointed model was used to simulate mechanical behaviour of the rock environment. The underground structure is driven in full -face with no lining. All the analysed alternatives are compared to one another considering the vertical displacement at the top of the underground structure and maximum vertical surface displacement. From the results presented, it can be concluded that from the point of view of vertical displacement at the top of the underground structure, situating the underground structure in the axis of the synclinal bend, if the dip of discontinuities is not very steep, is the least favourable. On the other hand, taking into account the maximum vertical surface displacement, situating the underground structure, in relation to the discontinuities orientation, seems to be of no importance.
