新疆阜康东抽水蓄能电站库区泥石流危险性评价OA

To assess the potential impact of debris flows on the Fukang East Pumped Storage Power Station project,based on geological data of the station area,combined with remote sensing interpretation and field investigation,this paper systematically analyzes the devel-opment characteristics of debris flows in major gullies such as the upper reservoir area,lower reservoir area and Sanchazi Gully.Through a multi-factor comprehensive hazard assessment method,the activity regularity of debris flows and their threat degree to engineering facil-ities are revealed.The results show that all debris flow gullies in the study area are at the mature stage and classified as low hazard level at the present stage,but they still have the possibility of initiation under heavy rainfall conditions;the impact load and sedimentation effect of debris flows may directly damage power station facilities,so targeted drainage projects need to be arranged.The research results can provide a scientific basis for debris flow risk prevention and control in the reservoir area and engineering safety design.
