Conclusion The investigations indicate the occurrence of considerable corrosion rates in rapidly flowing water of the penstocks of the
hydrostation with their rapid corrosion in the velocity range to 6 m/sec. A further increase of the flow velocity markedly
reduces the corrosion rate. The process of corrosion of steel depends in this case on the oxygen balance in the water and
on the relation between its stimulating and passivating effects. When selecting the operating regimes of penstocks it is necessary
to take into account this characteristic of the effect of oxygen on steel in fresh waters.

| 1. | The Zeya dam is in a satisfactory state, but is operating under conditions different from the design assumptions, under the effect of geodynamic forces — natural and induced seismicity with mainly a transverse direction of the earthquake and, probably, creep pressure from the right bank. |
| 2. | The design model of a plane stress state adopted in the design does not correspond to the real conditions of the static behavior of the structure which is in a volume stress state. The presence of dynamic loads requires determination of the dynamic characteristics of the structure and corresponding check calculations. |
| 3. | The geodynamic effect on the SSS of the dam requires improvement of the system of on-site observations and the organization of a geodynamic test area at the Zeya hydrostation in accordance with the decisions of the Ministry of Fuel and Energy of the Russian Federation. Before the creation of this test area the geodynamic effects should be monitored by the available measuring instruments according to the method of OIFZ and VNIIG. |
| 4. | The existing structural members of the deck of the cavities between buttresses require improvement with consideration of their new, antiseismic function, their incorporation into the calculation scheme, and equipping with measuring instruments. |
| 5. | The state of the dam and conditions of its operation require the creation of a mathematical model of the structure with consideration of the results of on-site observations and creation of a data bank for predictive purposes. |
