摘要
考虑到地震荷载作用下饱和黄土的孔隙水压力增长模式及液化规律,建立了饱和黄土无限边坡的动力稳定性分析模型。分析结果表明,此类边坡的失稳可分为液化型失稳和滑动型失稳两种基本形式,并给出了二者的判别指标。
Based on the increasing mode of pore pressure and liquefaction mechanism of saturated loess, a model to analyse the dynamic stability of infinite slopes of saturated loess is presented. By using the present model, the failure of these slopes is classified into two modes: one due to liquefaction and another duo to sliding, which can be distinguished by a suggested index.
