Complex dynamic investigations of foundations for low-speed turbine units at nuclear power plants

  • Published:
Soil Mechanics and Foundation Engineering Aims and scope

Conclusions

1. Dynamic tests indicated that the dynamic flexibility of both types of foundations diminishes on the whole as the equipment is assembled.

2. During the startup and output adjustment of a turbine unit on both a foundation with lateral condensors and a foundation with basement condensors, the TFB system will itself be at relative rest. Acute resonance peaks are not observed and the vibration levels of the foundations do not exceed allowable values.
