摘要
云南省维西县美光村泥石流属典型的沟谷型泥石流,发育程度高,严重威胁美光村村民安全。本文分析了美光村泥石流形成区特征、流通区特征、堆积区特征。该泥石流的形成主要受地形条件、物源条件、水源条件等因素的影响,陡峭的地形使得泥石流得以迅猛下泻,丰富的松散物质为泥石流活动提供更多的物源,充足的降水为泥石流提供了水源和水动力条件。根据该泥石流的发育特征及形成条件,采用“谷坊坝+拦挡坝+格栅坝+护岸墙”工程措施进行防治。
The debris flow in Meiguang Village,Weixi County,Yunnan Province is a typical gully-type debris flow with a high degree of development,seriously threatening the safety of villagers.This paper analyzes the characteristics of the forming region,moving region,and accumulated region of the debris flow in Meiguang Village.The formation of this debris flow is primarily influenced by topographic conditions,provenance conditions,water source conditions and other factors.The steep terrain facilitates rapidly flowing of the debris flow,the abundant loose material provides more material sources for its activities,and the sufficient precipitation supplies water sources and hydrodynamic conditions.According to the development characteristics and formation conditions,engineering measures of"check dam+retaining dam+grille dam+reveille wall"are adopted for prevention and control.
