Hazard Evaluation and Prevention Measures of Debris Flow in Reservoir Area of Fukang Pumped Storage Power Station in Xinjiang
Based on the formation conditions and development characteristics of debris flow in Fukang pumping reservoir area,the static and dynamic characteristic values of four gully debris flows with great influence are determined through field investigation,remote sens-ing interpretation and field test.The multi-factor comprehensive model of debris flow is selected to evaluate the risk of debris flow,and the influence of debris flow on project safety is analyzed from two aspects.The comprehensive prevention and control system of"slope stabilization,blocking,silting stopping"is put forward.The results show that:Xichagou debris flow is the most dangerous,with a value of 0.43,which is classified as moderate in hazard;The influence of debris flow gully in reservoir area is mainly manifested as silt effect and impact effect;The three-dimensional comprehensive prevention and control system of"stabilization,blocking,stopping"has good control effect and is worthy of promotion and application.
