description: The work is devoted to the study of the problem of fire danger in tunnel structures. Special attention is paid to the protection of structural deformation joints through the use of effective flame retardant technologies. The research set the following goals: 1. Analysis of scientific research in the field of fire resistance of expansion joints in unprotected design and with the use of fire protection; 2. Conducting experimental studies of the PROMIZOL-Seam-Sh150/240-80 type "cord" fire barrier made of specially treated mineral basalt superfine fiber operating under deformation conditions; 3. Modeling of thermal effects on the deformation seam in the ELCUT with fire protection "PROMIZOL-Seam"; 4. Recommendations on the use of flame-retardant materials for expansion joints in tunnel structures. Experimental and numerical studies have been carried out, a computational and analytical assessment of the fire resistance of deformation seams has been obtained, the effect of fire-resistant sealing resistance to fire on deformation seams in tunnel structures has been estimated. An approximation of experimental data in the form of a mathematical dependence is obtained, a nomogram of heating of reinforced concrete slabs with a deformation seam is constructed. The simulation results correlate well with experimental studies, which makes it possible to predict the behavior of both unprotected deformation seams and fire protection with a fire barrier. The implementation of the results of the work will improve the quality of existing and developing regulatory documents, which will contribute to the creation of new technologies for ensuring fire safety of facilities.
