Conclusions
-
1.
The system developed for the field observations made it possible reliably to control the safety of the spillway dam during construction of the Dneproges-2 plant.
-
2.
Analysis of the field-observation data indicated the absence of adverse changes in the state of the Dneprovsk spillway dam, which for a long period was subjected to the action of the special conditions caused by construction of the Dneprogés-2 plant.
-
3.
In the construction joints and the foundation of the gravity dam, significant seasonal changes in the uplift pressure may occur. In this case, the stability and strength characteristics of the dam may periodically decrease during the winter, which must be taken into account for operating the structure.
