Abstract：The combination of gravity retaining wall and lattice framed anchor structure is one of typical high slope supporting methods, and the response of seismic displacement and seismic strain have become the problems that people pay more attention. Therefore, a slope model with the geometric scale of 1:8 was designed and a large-scale shaking table model test was performed to study these dynamic response characteristics. The results show that: The horizontal seismic displacement responses of retaining structures are excited mainly by the horizontal excitation acceleration. The response intensity of negative peak seismic displacement under X excitation and positive peak seismic displacement under XZ excitation are small. Under X- or/and XZ- excitation, the response intensity of positive peak seismic displacement are approximately equal to that of negative peak seismic displacement at excitation acceleration ≤0.6g; and at ＞0.6g, the response intensity of positive peak seismic displacement is greater than that of negative peak seismic displacement under X excitation; and it is opposite under XZ excitation. The response intensity of seismic permanent displacement under X- or/and XZ- excitation at ≤0.6g are small, but the response intensity at ＞0.6g increase rapidly with excitation acceleration. The permanent displacement under XZ excitation is slightly greater than that under X excitation but in opposite direction. The seismic displacement mode of gravity retaining wall is the coupling of slide and rotation, and the seismic mode transform is determined by the direction and intensity of seismic excitation; The seismic displacement mode of anchored beam is translation. The top of gravity retaining wall and anchored beam mainly present positive strain response under the horizontal seismic excitation.
