摘要:Numerical algorithms are presented for modeling bank
failures during reservoir flushing. The algorithms are based on
geotechnical theory and the limit equilibrium approach to find the
location and the depth of the slides. The actual movements of the
slides are based on the solution of the Navier-Stokes equations for
laminar flow with high viscosity. The models are implemented in
the SSIIM computer program, which also can be used for
modelling erosion of sediments from reservoirs. The bank failure
algorithms are tested on the Bodendorf hydropower reservoir in
Austria. Comparisons with measurements show that the resulting
slides were in the same order of magnitude as the observed ones.
However, some scatter on the locations were observed. The
algorithms were stable for thick sediment layers, but instabilities
were observed for thin sediment layers.
