Abstract The seismic behaviors of the slope reinforced with the multi-frame beam，anchor cables and double-row anti-slide piles were investigated with the large-scale shaking table model test. The earth pressure acting on the pile，the axis force in the anchor cable，the acceleration in the slope and the deformation of the frame-beam were measured under the action of El Centro and Wenchuan-Qingping earthquake waves. The anchors and anti-slide piles perform as a collaborative structure under earthquake. The earth pressure increases with the amplitude of input seismic waves. However，The variation of anchor cable prestress is related to the stability of the slope，its value decreases firstly and then increases. The acting point of the resultant force of the active earth pressure moves up to the position of l/2. The pivots of pile embedded bedrock are varied significantly. When the peak ground acceleration of input seismic wave is less than 0.5 g，the displacement response of the frame-beam is small and the acceleration amplification effect does not exist obviously below the pile in the middle part of slope. The damage characteristics of internal slope analyzed using the Hilbert marginal spectrum theory are in agreement with the measured data.

Key words： slope engineering anchor cable cooperative work mechanism anti-slide pile shaking table test marginal spectrum
