| 摘 要： | 兰州市是我国地质灾害最为严重的省会城市之一,而位于城区南部的伏龙坪、华林坪地区已成为兰州市主要的地质灾害易发区,根据最新调查结果表明,区内发育有滑坡43处,崩塌8处,不稳定斜坡68处,泥石流沟7条。已造成7人死亡,9人受伤,直接经济损失近800万元,潜在威胁近5764人、资产约29112万元。发生滑坡的斜坡体基本上均由黄土组成,坡高一般30～50m、坡度一般40°～60°,而且这些斜坡地带居住了许多居民,坡肩和坡脚削坡建房,修路等形成了临空面,为滑坡的形成提供良好的临空条件,并且斜坡上无序堆放垃圾、倾倒污水,在降水的诱发下,促使滑坡、崩塌发生。所以,对伏龙坪、华林坪地区地质灾害治理已是迫在眉睫,刻不容缓。
