A brief description of analytical methods used for seismic analysis of underground structures is given. The methods take into account deformation of tunnel linings caused by seismic waves propagating transversely to the tunnel axis. Different approaches used now for seismic design are compared, examples of calculation are given. Advantages and disadvantages of the approaches are discussed. A new approach to seismic design of underground objects located on the shallow depth or near interface of different rocks is p...

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...
