Abstract
The main natural and anthropogenic factors forming the specificity of environmental conditions in the underground environment, which affects the development of deformations and corrosion processes of transportation tunnels, are considered. Natural factors include radon intake, the presence of buried bogs and marshy rocks. Technogenic factors of underground space pollution are household dumps, sewage system leaks, cemeteries. On the example of some transit tunnels it is shown that engineering-geological and hydrogeological conditions, as well as geo-ecological situation determine the peculiarities of functioning of these structures. It is noted that the destruction of tunnel materials occurs mainly due to the biochemical factor.
