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。
Lanzhou is one of the capital cities with the most serious geological disasters in our country. The Fulongping and Hualinping areas in the southern part of the city have become the major geological disasters prone areas in Lanzhou. According to the latest survey results, there are landslides in the area 43, collapsed 8, 68 unstable slopes, debris flow ditch 7. It has caused 7 deaths and 9 wounded, nearly 8 million direct economic losses, nearly 5,764 potential threats and assets of about 291,120,000 yuan. The landslide slopes are basically composed of loess, the slope height is generally 30 ~ 50m, the slope is generally 40 ° ~ 60 °, and these slopes inhabited by many residents, slope and slope foot slope cut building, road repair and other forms The face of the plane, for the formation of landslides to provide good conditions for the sky, and disorderly piles of garbage on the slopes, dumping sewage, induced by precipitation, prompting landslides, collapse occurred. Therefore, the management of Fulongping, Hualinping geological disasters is imminent, urgent.
