In work problems application of theoretical methods mechanics continuous environment for calculation of displacement and deformations rocks are considered at a construction of tunnels. The basic attention is given the account in calculations of vertical asymmetry in distribution of displacement in a pedigree file round a tunnel. The short analysis of the reasons display such asymmetry is presented. The way of the account in calculations vertical asymmetry in distribution displacement over and under a tunnel on the basis phenomenological approach taking into account features of functions of distribution of deformations and the given natural supervision is offered.
