从加筋土挡土墙的特殊受力机理出发,对水平和竖向地震同时作用下加筋土挡墙进行了内部稳定性分析;研究了挡墙破裂面形状与位置,结合国内外一系列室内和现场足尺试验资料而确立了地震作用下加筋土挡墙的分析模型;通过挡墙的筋带拉断破坏和筋土粘着破坏分析,分别推导了加筋带的界限配筋率和临界长度计算公式,这两个公式能适用于多种实际的荷载工况（静力荷载和地震荷载）,公式计算结果与试验结果吻合良好,可为加筋土挡土墙工程抗震设计及动力分析提供一定参考。

Based on the special mechanism of reinforced earth retaining wall, this paper introduces the interior stability theory of reinforced earth retaining wall under horizontal and vertical seismic loads. The shape and location of the failure surface of retaining wall is also studied. Be based upon a series of laboratory experimentations and field examinations, this paper establishs an unified analysis model in order to analyse reinforced retaining wall under seismic loads Through the analysis of the rupture of reinforced bar and its adhesive invalid...
