Purpose: To assess the engineering condition of the Sukharny tunnel that is an important element of the operating railway. The paper describes the inspection and verification calculations in accordance with the current regulatory requirements for transport underground structures on Lozovo-Sevastopol railway in the Crimea. Methods: Inspection works were performed on the Sukharny Tunnel including measuring, visual inspection and instrument-aided examination. Results: Based on the results of the survey, the tunnel lining parameters were specified. The lining calculations were then carried out taking into account the specified structural parameters. The range of works performed allowed making important conclusions and recommendations on the technical condition of the tunnel structures. Practical significance: After its opening, the Lozovo-Sevastopol railway connected the city of Simferopol with the central part of Russia, and accelerated the reconstruction of Sevastopol and the Black Sea Fleet after the Crimean War. Currently, the railway is still in operation and it is an important transportation artery connecting the city of Sevastopol with the central part of Russia. In the current geopolitical situation, it is especially important to ensure uninterrupted operation of this artery, which would be difficult without proper technical maintenance of the tunnels on this railway. Therefore, the survey and calculation works conducted, conclusions and recommendations proposed have important practical implications.
