The problem of stress state evaluation is really actual for the underground structures been exploited for a long time. Stress and deformation monitoring give opportunity for hazard prevention and planning operation mode of the underground facility. One of the most common methods of deformation control is convergence measurement, but transformation of measured data into stress state of underground structures is quite difficult. A technique for stress state evaluation of underground structures on the base of the ana...

Interfaces of rocks with different mechanical properties influence on seismic stress field appearing in rock mass during the earthquake. This influence may increase seismic load applied to underground objects located near the interface, so it should be taking into account in seismic analysis of the structures. For this aim the problem of elasticity theory about stress state of the ring supporting an opening in the half-plane, which is united with a half-plane of another material is considered. Lengths of seismic w...
