Hydraulic Oscillations Caused by the Earthquake
Hydraulic ooscillations caused by hydraulic, electrical or mechanical excitations may provoke very strong pressure pulsations, power fluctuations and mechanical vibrations, especially if the resonance appears. Some of the cases are described in the paper. Extremely strong and massive hydrodynamic loads in a hydraulic system may also be provoked by an earthquake, which sets in motion water masses enclosed in the system. The designer of the systeM should always aware in mind this fact and take appropriate measures to prevent any possible accident. Two methods for computation of possible hydrodynamic loads in a system: the method of characteristics (MOC) and the transfer matrix method (TMM), in case of a typical earthquake (selected by the seismologists) are presented in this paper. The theory of transient flow was applied to two cases:-Bottom outlet of an existing dam,-Penstock and the bottom outlet of a low-head power plant.
