Abstract

The Cape Aokas situated in the oriental coastal region of Béjaïa city (Algeria). The cape takes its origin from the babor mountain chain to the Mediterranean Sea along the Aokas city. Its relief is characterized by abrupt slopes. On May 9th, 2005 rocks fall in large mass (20,000 to 30,000m3) from one of the walls constituting the cape, blocked traffic on a busy road (RN° 9) at the entrance of Aokas city. The excavation work of fallen rocks was quickly undertaken by the authorities: 23 days after the rock fall, the road was reopened to traffic. The topometric monitoring was be implemented between April and September 2014 during the summer. The reflection was started to find the best way to strength permanently the rocky slope. In this paper, we present a comparison between the stabilizing system applied to the rocky slope and an optimization proposal in both following cases: without earthquake and under reference earthquake solicitation.
奥卡斯角(Bsjaia)的岩石崩塌:岩石斜坡的地质研究贡献和加固
奥卡斯角位于东部沿海地区的Béjaïa市(阿尔及利亚)。海角的起源从巴博尔山脉到地中海,沿着奥卡斯市。它的地形以陡坡为特征。2005年5月9日,大量岩石(20,000至30,000立方米)从构成海角的其中一面墙上落下,阻塞了青冈市入口处一条繁忙道路(RN°9)的交通。当局迅速开展了碎石的挖掘工作:碎石坠落23天后,道路重新通车。地形监测于2014年4月至9月夏季实施。倒影开始寻找最好的方法来永久加固岩石斜坡。本文对无地震和参考地震条件下应用于岩质边坡的稳定系统和优化方案进行了比较。
