Study on the Vertical Acceleration Effect on Slope Stability
It is found from the earthquake statistics in recent decades that the vertical seismic oscillation of near field was strong. And even the recorded peak value of vertical seismic oscillation was far more than the peak value of horizontal seismic oscillation in some sites. In order to study the characteristics of vertical and horizontal seismic oscillation acceleration acted on the slope. Calculate the slope earthquake dynamic response characteristics under the horizontal and vertical seismic acceleration by the FLAC3D numerical analysis method. Compared the acceleration, velocity and the displacement amplification coefficient under two kinds of excitation. Analyzed the influence on seismic stability by the acceleration of different direction.
