English abstract

The subject of the study is the patterns of interaction and distribution of forces between reinforcement elements as fibers of a composite structure of regular struc- ture, as well as hydrogeodynamic, energy and geometric parameters of disturbed soil massifs during the restoration of destroyed infrastructure facilities. The purpose of the work is to simplify and speed up the commissioning of bridge structures with span structures destroyed as a result of military operations based on the scientific justification of a single complex technology for their rapid restoration using composite cable ropes of domestic production. As an alternative to the complete restoration of destroyed bridges, it is proposed to use cable-stayed structures in whole or in part. As bridge cables, it is proposed to use well-known rubber composite ropes, the production of which has been estab- lished in Ukraine. The reliability of the proposed ropes can be increased by increas- ing the number of ropes in them. A model and algorithm for calculating the stress-deformed state of a rubber ca- ble rope of an arbitrary design has been developed, taking into account the non- linear deformation of the cables and the presence of a discontinuity of an arbitrarily located cable. The model was built using the methods of mechanics of composite materials. It is solved analytically in a closed form.
