摘要目前对该结构的动力特性和工作机制的研究还不完善，为了能够准确、合理地对该新型边坡锚固结构地震作用进行分析与设计，深入开展其动力特性及抗震设计理论研究是非常必要的。在预应力锚杆锚固作用下，框架受力满足弹性地基梁工作原理，因此，采用Winkler弹性地基梁理论，建立地震作用下框架预应力锚杆边坡锚固结构的动力计算模型。考虑梁和挡土板的影响，推导出外框架–预应力锚杆–坡后土体三者协同工作的水平地震动力运动方程，获得解析解。最后，结合工程实例，采用本计算方法进行地震动力响应分析，并与数值模拟、振动台试验进行对比验证，结果吻合较好，表明提出的方法是有效、可靠的。通过对支护和未支护边坡分析发现该结构能够明显控制地震响应，抗震性能表现良好。提出的计算模型为框架预应力锚杆边坡锚固结构的地震动力分析与设计奠定理论基础。

Abstract：In order to accurately carry out dynamic analysis and seismic design of the new slope anchorage structure，the study of its dynamic properties and seismic design theory is very necessary and urgent. The movement characteristics satisfy the theory of elastic foundation beam under the prestressed anchor action. A dynamic calculation model of frame with prestressed anchors for slope stability is established based on Winkle elastic beam theory. Under the horizontal earthquake excitation，the equation of vibration for slope supported by frame with prestressed anchors and slope is deduced considering the influence of beam and retaining plate，and the analytical solution is obtained. Finally，the proposed method is applied to a project case for illustrating its capability of earthquake response. In order to investigate the effectiveness and reliability of this method，it is compared with finite element method and shaking table test，the results show a good agreement. The analysis of slope with supporting and without supporting reveals that this structure can evidently decrease the earthquake response and has better seismic performance. The calculation model provides a new approach for earthquake analysis and seismic design of slope supported by frame supporting structure with prestressed anchor.

Key words： slope engineering frame beam prestressed anchors seismic effect dynamic calculation model earthquake response
