Abstract To study the deformation mechanism and acceleration response of the multi-sliding surface landslide body under the action of vertical earthquakes，take the seventh block of the Yushu Airport Road landslide group #0 landslide as an example，we carried out shaking tables test under 4 earthquake intensities and 4 loading conditions. The model test focuses on the horizontal and vertical accelerations peak and time-history curves of the multi-slip surface landslide body subjected to vertical excitation，and then analyzes the deformation and failure mechanism of the multi-slip surface landslide body . The results show that：with the continuous increase of the input seismic wave energy，the acceleration peak of each measurement point increases obviously. Along the sliding belt，with the continuous increase of the elevation，the acceleration peak increases gradually. In the vertical section A6–1‐A6–4 points，the acceleration peak inside the sliding zone is greater than the bedrock and sliding body，and the sliding zone has a certain absorption effect on seismic wave energy. The vertical acceleration peak inside the sliding zone is approximately horizontal 2 to 6 times.

Key words： slope engineering vertical excitation acceleration response shaking table test
