AbstractIn recent years at the many hydro-electric stations erected on the Dnieper, the Volga and the Kama, emissions of combustible gases were detected in the concrete foundations of the structures, during the second and third year after the filling of the reservoirs. In the gas formation, methane and nitrogen predominate and more rarely, hydrogen. This phenomenon had not been investigated. In this article the results of research into the occurrence of gas in the foundations of the Kama hydro-electric station are explained, also some information is given on the chemical composition of the gases at the V.I. Lenin hydro-electric station on the Dnieper, the V.I. Lenin hydro-electric station on the Volga, and the 22nd KPSS Convention station on the Volga, where the author became acquainted with the phenomenon under natural conditions.
