摘　　要：通过对云南省维西县梓里沟泥石流进行现场调查,获取了梓里沟泥石流相关的数据资料,据此分别对梓里沟泥石流的容重、流速、流量、冲击力等动力学特征参数进行计算。计算结果表明:在不同爆发频率下,泥石流动力特征参数不同,且相差较大;在同一爆发频率下,不同沟段处,泥石流的动力特征参数也是不同的。By the site investigation of the debris flow disaster Zili gully in weixi, Yunnan, the first-hand data of the disaster was obtained. The mud-rock volume-weight, flow, flow velocity, impact of Zili gully were analyzed and calculated based on these collected data. The calculation results show that the dynamic characteristic parameters of debris flow are different, and a big difference. The dynamic characteristic parameters of debris flow are different at the same frequency.
