Abstract
The mountainous area is wide in the western region of China, and there are many seismic zones. Due to the two factors, there are more and more slope projects in the western region, and the influence of earthquake also need to be considered into the relevant researches on anchored slope. The damage to the slope under the earthquake has attracted the attention of researchers, Therefore, there are many studies on slope support under the seismic action. However, there is little research on the influence of seismic intensity on the slopes supported with pre-stressed anchored-frame structures. This paper based on an engineering example in the northwest loess area, taking into account the synergy of the frame-anchor-soil, a three-dimensional finite element model of the slope system with pre-stressed anchored-frame structure under the seismic action was established. The dynamic response of the supported slope was calculated by the finite element software ADINA, and the impact of different seismic intensities on the slope displacement, acceleration, axial force of anchor, and earth pressure are analyzed
