川西北德格县隆达沟泥石流的基本特征、成因及防治

摘要

Based on the analysis of ifeld geological survey, basic characteristics and major dynamic parameters, we discuss the genesis of the Longdagou debris lfow in Dege country, southwestern Sichuan. We suggest that the possibility of emergence of the Longdagou debris lfow will exist while the rainstorm encounters under 5%frequency or beyond the design frequency. Then we put forward the comprehensive engineering measures of“blocking dam and protective dike”to prevent the debris lfow breaking out again.%在野外调查、基本特征和主要动力学参数分析的基础上，探讨隆达沟泥石流的成因机制，认为在暴雨强度为20年一遇及其以上设计频率时具有泥石流发生的可能性。进而提出“拦挡坝＋防护堤”的综合治理工程来预防泥石流的再次爆发。
