The application package with which help the behaviour of a curve creeping for loose excavation and a curve relaxation of strain was investigated in case of a rigid timbering is created. Are investigated change of a configu-ration of loose of elliptic excavation section depending on time of her maintenance, and also distribution of strain at a rigid timbering of excavation. The technique of problem solving of a diffractional dissipation of elastic waves of longitudinal displacement on tunnel cavities of circular section with the elastic or rigid fixed inclusions of sector sections in orthotropic or anisotropic arrays is constructed.
