Seismic stability of a hydro power plant in Switzerland
Abstract
Seismic stability of a hydro power plant in Switzerland The hydropower plant is located several kilometers upstream from a nuclear power plant. Therefore the seismic stability of the hydropower plant is highly relevant for the safety of the nuclear power plant. The hydropower plant is in a seismically active region. The safety of the hydropower plant particularly the safety against sliding along the base will be studied in this project. The dam and the machine house are in an inhomogeneous ground with inter-bedded sand stone, clay stone and silt stone. The shear strength, particularly the cohesion plays an important role for the stability against sliding. The stability will be investigated with a typical signal of the Peak Ground Acceleration. A return period of 10,000 years is assumed, which is different from the Eurocode 8, where a return period of 475 years is used. The residual displacement is calculated based on the method of Newmark and its relevance for the stability of the hydropower plant is discussed.
