A Preliminary Study on Distribution Law of Lateral Earthquake Load Along Slope's Height

Abstract eng:
Total 18 simulated acceleration time histories for intensity 6, 7, 8 and 9 were adopted as inputs, two different height slops which were located in some power station area were selected as the analyzed models which were simplified linear elastic models in computation, the seismic responses of the slopes and the horizontal variation of the maximum response accelerations at different height levels were analyzed by means of a wave propagation finite element method. The numerical results show that the acceleration changes along the height direction nonlinearly with a little bit complicated pattern, and the changing patterns, in general, are similar. The acceleration does not increase immediately after the slopes’ height is getting taller from the bottom of the slopes, and it starts to increase rapidly with the height level at a height of half to two thirds of the total slopes’ height. It gets a maximum amplification value of 1.0 to 1.91 at the top of the slopes. In general, the maximum amplification factor increases gradually with the total height of the slopes, and just a few get values greater than
