摘　　要：岩坡滑坡是我国常见的地震灾害类型,其严重威胁到人民生命及基础设施的安全,因此针对震区岩坡的稳定性分析尤为重要。近几十年来,国内外学者针对岩坡在地震作用下的安全稳定性展开了相关研究工作,并取得了丰硕的成果。从岩坡稳定性分析着手,从理论分析法、Newmark滑块位移法、数值模拟法、振动台试验等方面,分别阐述了目前国内外地震作用下岩坡稳定性分析的研究现状与发展。结果显示,现有含软弱夹层岩坡稳定性研究中多将软弱夹层简化为一个平面而忽略其厚度、力学特征,同时较少考虑软弱夹层自身特性、多层滑移现象以及地下水等复杂地层特征等条件对岩坡稳定性的影响。Rock slope landslide induced by earthquake is a common type of earthquake disaster in China,which seriously threatens the safety of human life and infrastructure.Therefore,it is particularly important for the stability analysis of the rock slopes in seismic area.In recent decades,scholars all over the world have carried out relevant researches on the safety and stability of the rock slope under seismic conditions and achieved fruitful results.Based on the analysis of rock slope stability,this paper expounds the research status and development of the stability analysis of rock slope under seismic conditions at home and abroad from the aspects of theoretical analysis,Newmark sliding-block displacement method,numerical simulation method,and shaking table test.The results show that in the existing studies on the stability of rock slope with weak interlayer,the weak interlayer is simplified as a plane mostly and its thickness and mechanical characteristics are ignored.Meanwhile,the influences of the characteristics of weak interlayer,multi-layer slip phenomenon and complex stratum characteristics such as groundwater on the stability of rock slope are seldom considered.
