| 摘 要： | 以雅泸高速公路K136＋150～K136＋300 m段反倾向岩质边坡为例,采用基于离散元法原理的计算软件——UDEC,在充分研究边坡工程地质条件的基础上,模拟研究了反倾向岩质边坡在地震作用下的变形破坏机制及失稳破坏模式,进而分析了边坡的稳定性。结果表明：边坡在地震作用下其变形破坏是＂岩体松动→倾倒→崩塌＂的过程,此过程经历的时间较短,往往是在振动持时内完成。

| Abstract: | The reversed rock slope in Section K136＋150—K136＋300 m of Yalu Expressway is studied,considering geological engineering conditions.Using the software named UDEC which is based on the discrete element method,the deformation and failure mechanism are simulated to analyse the stability of the slope.The result reveals that the process of deformation and collapse are caused in the process of loosing,dumping and collapsing.The process can usually happen during the earthquake,and last for a short time. |
