Abstract: This paper examines the seismic response of soil landslide supported with micropiles. It is based on tests of large-scale shaking table. A landslide model with a scale of 8: 1 is made. The El Centro wave, Wenchuna wave, Kobe wave and Sinusoidal wave are regarded as the seismic excitation. The landslide failure characteristics and acceleration response under the seismic waves were analyzed. The test results indicate the following findings. (1) The failure pattern of micropile after earthquake shows the reverse "S"-type, which is similar to that under static loads. The destruction area of micropile mainly distributes in 1.4-4 times pile diameter above the sliding surface and 1.4-3.4 times pile diameter below the sliding surface. (2) Acceleration response is different under different seismic waves with different spectrum characteristics. The closer excitation frequency to the natural frequency of landslide, the stronger the dynamic response of the landslide. The acceleration response of the landslide with micropiles has obvious elevation amplification effect. The higher the excitation frequency is, the more significant the elevation effect is. (3) Micropiles can suppress seismic waves. The acceleration in landslide surface that supported by micropiles is weaker than that inside the landslide(especially the landslide toe). However, with the increase of height, it ends to weaken, consequently, the upper part without supporting structure has surface effect.
