青海省牛犁壕沟泥石流动力学特征及危险性评价

Debris flow dynamic characters and its hazard risk assessment in Niulihaogou of Qinghai

在对牛犁壕沟进行野外调查的基础上,通过对牛犁壕沟泥石流发育特征、成因分析、动力学特征参数计算及危险度评价研究,认为该沟属于中等危险的泥石流沟,还有爆发泥石流的可能性,并提出了"上游稳坡固源拦挡、中下游排导"的工程治理措施。

Based on the field investigation of Niulihaogou,the characteristics,causes,dynamic characteristic parameters,and hazard degree assessment of debris flow are analyzed. The conclusions are that it is a medium dangerous debris flow gully and there is the possibility of debris flow outbreak,and the ＂fixing upstream slope to cut the debris flow source,discharging in middle and lower stream ＂engineering treatment measures is proposed.
