Research on the Anti-silting Design Approach and Application in the Drainage Canal of Debris Flow
摘要
Abstract
Drainage canal is a conventional mitigation and control works of debris flow, of which mitigation efficiency will be immensely influenced due to the debris flow silting in it. Until now there is no illustration about the calculation of its silting in the domestic reference standards, which causes the drainage canal silting accidents occur occasionally. In the view of this, the common causes of drainage canal silting are analyzed, and a serious silting check calculation formulas are advanced, then a set of drainage canal silting check calculation method based on canal width check, mud depth check, velocity check are proposed. This approach was applied in the silting accident removal of debris flow drainage canal at Sekeniluo valley along the Yalu highway under construction, the rebuilt drainage canal also withstand the debris flow caused by the torrential rain at Jan. 17. 2011, which means that the approach is well-responded and can serve as a reference for related research and engineering design.关键词
