| 摘 要： | 针对拟静力法的边坡传统抗震设计方法存在一些不足之处，基于强度折减动力分析法，提出一种边坡抗震设计新方法，该方法考虑了支护结构与岩土体在地震作用下的动力相互作用，能够满足边坡抗震和静力稳定性设计要求，利用该方法可得出支护结构的内力，确保了工程设计的安全性和经济性。通过对成都-兰州(成兰)铁路茂县车站高边坡抗震设计，描述该方法的具体实施过程，论证了此法的可行性，为支护边坡的抗震设计提供了一种新思路。

| Abstract: | In traditional seismic design of slope，the most commonly used method is the pseudo-static method. Because of its limitations，a new method of seismic design of the slope is proposed based on the strength reduction dynamic analysis. The proposed method takes into account the interaction between the supporting structure and rock soil under earthquake. It can satisfy the design requirements of earthquake and static stability of slope. The internal forces of supporting structure are obtained by the method. So，it ensures the safety and economics of engineering design. The seismic design of high slope of Mao railway station demonstrates the feasibility of the proposed method in practice，which provides a new idea for the seismic design of retaining the slope. |
