This task becomes particularly relevant at the intersection of bridge and tunnel structures connected by a single geotechnical environment. The interaction of such objects can lead to a redistribution of stresses in the soil mass, additional deformations of the foundations and a change in the stress-strain state of the lining.<\/p>\n<p style=\"text-align: justify;\">Using the example of a real viaduct located above an existing transport tunnel and an adit, the article examines the features of assessing their mutual geotechnical influence in a static setting. The impact calculations were performed in a three-dimensional model in the GTS NX program.<\/p>\n<p style=\"text-align: justify;\">The cases of loading a viaduct with operational loads and impacts are considered, and it is established that the stress-strain state of the supporting structures of the tunnel and the tunnel practically does not change when they are applied. The emergency situation of a train falling from a viaduct is considered, according to the calculation results, the additional efforts in the lining of the tunnel and tunnel do not exceed the efforts under seismic influences and are not dangerous. At the same time, changes in the soil environment around the tunnel, associated with decompression, removal of soil into the tunnel space, damage to lining and dumping of soil leads to damage to the foundations of the viaduct, rolls of supports and disruption of the geometry of the path on the viaduct.<\/p>\n<p style=\"text-align: justify;\">The article develops proposals for geotechnical monitoring of the viaduct to ensure the safe operation of the transport system.<\/p>\n<p style=\"text-align: justify;\"><strong>Keywords:<\/strong> geotechnical impact; tunnel; cast iron lining; bridge; viaduct; foundation damage; drilling poles; impact; locomotive fall; geotechnical monitoring<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Baranov Timofey Mihailovich Irkutsk State Transport University, Irkutsk, Russia E-mail: Baranov-87@yandex.ru ORCID: https:\/\/orcid.org\/0000-0003-3981-6413 RSCI: https:\/\/elibrary.ru\/author_profile.asp?id=926740 Abstract.
