摘要
吉林省通化县二密铜矿磨房沟泥石流位于沟谷内,沟谷内的卵石、漂石层被水浸润饱和,在洪水的托动下,由高向低流动,形成泥石流。与此同时,裸露的岩石受到了长期风化剥蚀,地表水易于渗入,由于失去了植被对松散固体物质的固结作用,风化岩土体以坡面侵蚀方式为泥石流形成提供了大量的固体物质。防治工程措施为淤积物清理工程、修建谷坊工程、导流槽工程、简易盖板桥工程、原破损路面修复工程。
The Mofanggou debris flow in Ermi copper mine in Tonghua County,Jilin Province is located in the valley.The pebbles and boulders in the valley are saturated by water,and under the support of floods,they flow from high to low,forming debris flow.At the same time,exposed rocks have been weathered and denuded for a long time,and surface water is easy to penetrate.Due to the loss of vegetation s consolidation effect on loose solid materials,weathered rock and soil provide a large amount of solid material for the formation of debris flow through slope erosion.The prevention and control engineering measures include sludge cleaning project,valley building project,diversion channel project,simple slab bridge cover project and original damaged pavement repair project.
