Based on existing data of experimental studies of underground structure-soil interaction, a condition for boundary interaction between the underground pipeline and soil was developed. The proposed condition (a model) of interaction at the contact boundary takes into account the structural destruction of the contact soil layer and the cyclical nature of interaction process. The authors have shown by parametric analysis of the interaction model, that under cyclic interaction of the underground pipeline with soil, the structural disturbance of the soil contact layer does not reach the peak shear stress; the applicability of the problems of underground structure-soil interaction is also shown. The model of interaction on the contact structure-soil surface in particular cases passes into the existing conditions of interaction, including Coulomb friction.
