摘要

干河沟为一老泥石流沟,曾于1996年8月暴发较大规模泥石流冲毁沟口红灯桥及木材厂。"5.12"地震后流域内新增大量松散物源,以崩滑体为主,主要集中于3~#沟,物源丰富,动储量约26×10~4m~3。该沟泥石流一次冲出固体物质量较大,大于2万m~2,规模大型。结合该沟泥石流的发育特征,提出了相关的防治措施及建议。
Ganhe gully which is an old debris flow gully had broken out on August,1996.The disaster destroyed the Red light bridge and lumber mill at the gully mouth.According to the investigation on the debris flows,it is found that the gully has rich matter-source which are concentrated in 3 # gully region after 5.12 Wenchuan earthquake.The main kind of matter-source are rock fall and landslide,the dynamic reserves is about 260 000 m3.The debris flow is defined as large-scale with 20 000 m3solid matter bursting out Combining with the construction characteristics of Ganhe debris flow gully,this paper proposes related controlling measures and suggestions.
