STUDY ON DYNAMIC CHARACTERISTIC AND CONTROL MEASURES OF JINZIGOU DEBRIS FLOW IN YUNNAN PROVINCE NINGLANG COUNTY

Jinzigou debris flow is a high-frequency prone gully debris flow in the high altitude area of the north-west Yunnan, its tributary more development, Channel longitudinal gradient big, source mainly in the upstream of the gully(active gully) on both sides of the landslides, avalanches, glacial till, and channel slope diluvium piled up slow early in the diluvium, debris.it has abundant loose sediment supply source, great catchment area, and might cause serious damage to it and the downstream villages. It is a high susceptibility to gully debris flow, on the basis of geology investigation, Scale and scope of the investigation disaster debris flow, and analyze their development characteristics and breaking strength, field investigation and simulation test, Determine the physical characteristics of debris flow and the corresponding value of the formula, debris flows were calculated flow rate, flow, a process and impact force of the total kinetic parameters, and then, the debris flow velocity, impact force, climbing height, and the total amount of a large viscous debris flow are the characteristics of the debris flow., According to its climate, the comprehensive engineering control measures of stable block based, sparse discharge auxiliary, bnding kinetics studies, without reducing the control effect of the premise, can effectively reduce the amount of control engineering and engineering investment, the reasonable prevention and control measures are put forward after further research. The achievements have some reference value for the similar mechanism debris flows.
