【摘要】 以某工程边坡为例,采用人工合成地震动为输入条件,运用FLAC^2D进行边坡岩体的全时程动力分析,探讨地震作用下边坡岩体的动力响应规律及稳定性。数值模拟结果表明:在地震动力作用下,边坡发生大变形（大于3.0m）,塑性区沿覆盖层与基岩界面分布,界面岩土体发生塑性破坏,会发生整体性的远程滑动,必须采取措施进行综合治理,这一结论对处置库的选择和建设具有重要的工程应用价值。更多还原

【Abstract】 Taking the slope of A Engineer for example,the dynamic response and failure mechanism of slope rock mass under seismic loading are simulated by FLAC.The time-history curve of artificially synthetic acceleration is used.The following results are obtained:under the seismic dynamic load,the side slope could form a large deformation (greater than 3.0m),the plastic zone is distributed between the capping and the interface of the bedrock,the rock and soil of the interface can form a plastic collapse,causing a long-distance landslide,so the comprehensive control measures must be taken.This conclusion has important application value for the selection and construction of the repository.更多还原
