摘要

四川省黑水县红水沟泥石流位于色尔古水电站闸(坝)址上游右岸约500 m处

严重影响着该水电站的安全

因此必须对红水沟泥石流进行重点研究。在现场勘察调查的基础上

对红水沟泥石流的成因、动力特征和危险性进行了详细的分析评估

研究表明

红水沟泥石流形成的物源条件、降雨条件和地势条件均满足泥石流的形成条件

且形成条件充分。该泥石流的规模中等

危险程度高

有进一步发展趋势。

Abstract

Debris flow in Hongshui valley located in the upper area of Seregu hydropower station in Heishui County

Sichuan Province is studied.Based on the survey of the debris flow site

the formation conditions of debris flow and its dynamics features are analyzed and its hazard assessment is made.Results show that the material factor

rainfall factor

and physical feature satisfy the formation conditions of debris flow in the valley.The formation conditions are sufficient and the scale is medium.Its hazard degree is high and its development trend has been accelerated.
