Conclusions
1. Systematic geodesic observations of static deformations should be organized in constructing foundations for turbine units at high-capacity nuclear power plants; the results of these observations will ensure attainment of the required operational control data during construction and operation.
2. During the design of these foundations, it is necessary to consider the installation of special surficial and deep marks for the organization of observations on bed settlement, beginning from the moment when the lower concrete slab is poured.
3. In placing distributive cushions for the foundations, it is necessary to provide for a high quality of compaction within the bounds of the entire lower surface of the foundation and for careful geotechnical control.
4. In designing foundations for turbine units on inhomogeneous beds, we should consider the difference in the rheological properties of the soils, the character and sequence of bed loading, and the variations in its hydrogeologic regime in order to exclude nonuniform settlements during equipment assembly and operation of the machinery.
