摘　　要：降雨是滑坡失稳破坏的主要诱发因素,回头沟滑坡位于广元市朝天镇双河村,是典型的降雨诱发的顺层岩质滑坡。在研究了回头沟滑坡的工程地质条件及滑坡的基本特征的基础上,介绍了"7.23"降雨过程滑坡的变形破坏特征,论述了滑坡—堰塞湖灾害链效应,分析了滑坡的失稳破坏模式,并对滑坡的稳定性做了工程地质分析,结合工程实际提出了回头沟滑坡防治措施。Rainfall is the main predisposing factors of destroyed landslide.Huitou Groove landslide is located in the district of Huitou Groove village,Chaotian town,Guangyuan city,which is a typical rainfall-induced rock bedded landslide.On the study of engineering geological conditions and the basic characteristics of landslide,this paper introduces the deformation characteristics of landslide during ＂7.23＂ rainfall process,the disaster chain effect of landslide dammed lake,analyzes the landslide instability and failure mode,and makes an engineering geological analysis to the stability of landslide.Combining with practical engineering examples,it puts forward the prevention and control measures to Huitou Groove landslide.
