Dynamic response test and numerical analysis of anchored slope under earthquake action
The 1∶7 scale model shaking table test is adopted to explore the dynamic response law of the anchored soil slope un-der dynamic action.Inputting Kobe wave,Wenchuan wave and El Centro wave in the test and monitoring the slope acceleration to study the response law of the anchored slope acceleration and the effect of ground motion parameters(the seismic wave type and the seismic wave amplitude)on the slope acceleration.The experimental results were validated using numerical simulation methods.The results show that under the dynamic action,the anchored slope has obvious amplification effect in the vertical direction,and the dy-namic response is the strongest at the top of the slope,while the amplification effect of the slope in the horizontal direction is not obvi-ous.When different types of seismic wave are input,the dynamic acceleration response of the anchored slope under the action of Kobe wave is the highest,while the Wenchuan wave is the lowest.For the same seismic wave,with the increase of seismic wave intensity,the amplification coefficient of PGA at each measuring point shows a trend of"decreasing first and then increasing",and the trend of change at the top of the slope is more obvious.
