摘要	Based on the principles of soil dynamics and structural dynamics, a ground motion analysis model of a slope reinforced by a frame with prestressed anchors is established, and the dynamic response of the reinforced slope under horizontal earthquake action is obtained. In this paper, based on the horizontal strip method, the slope height is considered as an influencing factor, and the dynamic analysis model for soil pressure of the slope under earthquake action is developed. When establishing the ground motion analysis model of the reinforced structure, the model was based on the lumped mass method, considering the prestress of the anchors; a frame column is used as a calculation unit to form a concentrated mass string, an anchor is connected with the soil in the form of an elastic support, and prestress is applied to each anchor by a given initial design value. According to the assumed prerequisites proposed above, a structural power control balance equation is established. The axial force response of a prestressed anchor is solved by applying the soil dynamic pressure, prestress and seismic action to the frame structure. The soil pressure distribution characteristics of the reinforced slope system, the displacement response of the reinforcement structure, and the axial force response characteristics of the prestressed anchor can be approximated with this model. The model provides a basis for the seismic design of a slope reinforced by a frame with prestressed anchors.
