新型悬挑式泥石流网格格栅坝及其应用

悬挑式网格格栅坝是从工程实践中在传统网格格栅坝的基础上演变而来的一种新型的格栅坝体类型,该种坝型继承了网格格栅坝的各种优点,并且通过悬挑格栅的独特设计,更具突出在非排导泥石流时对河流沟谷地的常态水流进行非拦截性排流,使河流沟谷内常态水流更为通畅,不会干扰河流沟谷的正常流通,是传统网格格栅坝的优化坝型,均适用刚性和柔性网格材料筑坝。目前国内还没有该种坝型的研究成果和相关技术资料,文章通过阐述其在以水流为主的稀性泥石流和挟带大量推移质的高含沙洪水的泥石流治理工程中的应用研究,得出该坝型的优缺点和相关技术成果,作为进一步工程实践和研究提供基础技术依据,从而进行悬挑式网格格栅坝在泥石流防治工作中的应用和推广。

The study and application of new type jettied crib dam

Jettied crib dam is a new type of dam which designed based on traditional crib dam,It＇s not only has the advantages of traditional crib dam,but also make the river corridor more smoothly,It＇s better than traditional dam,applies to both rigid and flexible grid material by special design. At present,there is no research results of this new kind of jettied crib dam,This article described advantage of debris flow training works while Jettied crib dam against different type debris flow（ diluents,high sediment）,combining from actual projects as design practices to extension in debris flow training works. Advantages and disadvantages research progress in this kind of dam is reviewed. It has widespread application and extended value.
