云南省维西县二道河泥石流至今已有数百年历史 ,近年来 ,随着人类活动对自然环境的破坏加剧 ,生态环境日趋恶化 ,泥石流几乎年年都爆发 ,且次次造成灾害。 2 0世纪 90年代初中期曾进行过治理 ,基本控制了泥石流灾害的漫延和发展。但在二道河泥石流汇入永春河处 ,输砂能力差、堵河严重 ,使排导槽向上游回淤、漫槽形成灾害。本文针对二道河泥石流灾害的特点 ,综合多方面的比选结果 ,采用以V型槽排导为主的最佳续治方案。
In recent years, as the destruction of natural environment by human activities intensified and the ecological environment deteriorated day by day, the debris flow broke out almost every year, and the second time caused the disaster. In the mid-1990s, the government conducted the control and basically controlled the spread and development of the debris flow disaster. However, the Erdaogo debris flow into the Yongchun River Department, poor sand conveying capacity, blocking the river serious, so that the drainage channel to the upper silt, diffuse channel formation disaster. In this paper, according to the characteristics of Erdaogu debris flow disaster, comprehensive selection of many aspects, the use of V-groove guide the best continuation of the program.
