This article based on the practical engineering in the northwest loess area in China, considered the interaction and collaborative work of frame-anchor-soil, with the help of the finite element software ADINA, established a 3D finite element model of the frame prestressed anchor supporting slope system under earthquake action. In the model, the soil was simulated by elastic-plastic model, and a bilinear elastic model was used to simulate the anchor, friction-element was used to describe the interaction between soil and frame (beams, columns and retaining plate), the frame is simulated by a bilinear elastic-plastic model. By inputting bidirectional seismic waves, the dynamic response of the supporting system under different horizontal and vertical spacing of anchors was compared and analyzed. Finally, obtained the influence law of different anchor spacing on the slope seismic response.
