泥石流多发区引水工程渠首泥砂灾害试验研究——以云南东川团结渠首为例

Experimental Study on Sediment Diesasters of Canal Headwork in Debris Region -A Case Study in Tuanjie Channel of Yunnan Province

本文以云南东川团结渠首为研究对象 ,对泥石流多发区引水工程泥沙灾害形成条件进行分析 ,通过渠首型试验研究 ,并结合野外实地踏勘资料综合分析 ,提出了渠首泥沙灾害防治的工程方案和技术措施 。

This paper presents the enviromental features of forming debris flow,analyses the distribution regularities of time and space for sedimdent motiom in Tuanjie water engineering region,and discrsses the causes of sediment disasters ofcanal headork in debris region.On the basis of model tests,the relevant data of the test onprevention construction and field invetigation,a rationala engineering progra mme against sediment disasters has been obtained.The results of this study provides a theoretical foudation for prediction,prevevtion and control of seediment disasters.
