甘肃武都马槽沟滑坡特征及治理对策
|
摘要
甘肃武都地区新构造和地震活跃,降雨集中且多为暴雨,加之地形复杂,人地矛盾紧张,因而生态环境恶劣,这为滑坡地质灾害的发育提供了条件。为了有效地防灾减灾,本文以马槽沟滑坡为典型实例,从滑坡形态特征、形成条件、触发因素等角度入手,阐述了该区滑坡发生的机理,在此基础上对当前滑坡所处的稳定程度进行了分析。并提出了滑坡工程治理的具体方案,以期对该地区滑坡防治有参考价值。
In Gansu Wudu the new structure and the earthquake are active,the rainfalls are concentrating and often as rainstorms,the terrain is complex,and the activities are human instensive,thus the ecological environment is bad there,which has provided the condition for the landslide geology disaster growth.In order to carrying out disaster prevention and reduction effectively,this article takes the Macaogou village landslide as a typical example,from distortion characteristics,forming conditions,triggering factors,to elaborat this area landslide mechanism,and assess the landslide stability.The paper proposed a landslide concrete scheme to the government,and could be of reference value for geological disasters control.
