Conclusions
-
1.
The investigations showed a high effectiveness of dynamic tests of concrete dams by the vibration machine. Such tests make it possible to determine the dynamic characteristics of the structure with a high accuracy and on this basis to refine its calculation scheme.
-
2.
The investigations showed that in dynamic calculations of concrete gravity dams it is necessary to take into account the three-dimensional character of behavior of the structure (interaction of the sections) and to estimate the forces occurring in the intersectional joints for checking the strength of the intersectional seals.
