Abstract: In order to more finely simulate the seismic response of concrete dams at stepped terrain dam sites under consideration of multiple factors such as material nonlinearity and reservoir bottom absorption coupling, it is necessary to develop applicable dynamic models for dam-reservoir water-foundation nonlinear interactions, of which reasonable ground vibration input is one of the primary problems faced.Based on the wave field separation principle and the stress free condition on the slope surface,... More
