Studies of the interaction between seismic blast waves and underground structures are conducted to select boundary conditions on the contact surface between these structures and the soil. In relation to this, a law governing longitudinal interaction between an elongated underground structure and the soil which, among other things, combines condition with Coulomb's dry-friction law, permitting slippage of underground structure relative to the soil, is proposed in this paper. The present study is devoted to experimental determination of the adaptability of conditions (expressed here as equations) at the contact boundary between elongated underground structures and the soil under dynamic (seismic, blast) effects along the axis of the structure. Experiments with large-scale underground structures (tunnels, subways, etc.) were conducted under difficult conditions to ascertain the law governing their interaction with the soil under dynamic or static effects. Values of the tangential stresses on the contact surface between the steel pipe and soil were determined from longitudinal-force recordings.
