| 摘 要： | 受汶川地震影响,四川等地泥石流治理更为迫切.泥石流的暴发具有突发性,在防治工程中,相比实体坝而言,格栅坝是一种节省材料、稳定性更高的拦挡结构,使用范围越来越广,但是目前尚无成熟的格栅坝设计方法.本文参考梳齿坝的已有理论确定了支墩间距的计算方法,并结合已有实验资料提出了格栅坝格栅间距的计算公式,改变了以往不同坝体乃至同一...

| Abstract: | Under the influence of Wenchuan earthquake,it is more urgent to prevent and control debris flows in many provinces especially in Sichuan.The outbreak of debris flows has suddenness,now we give first place to its prevention.Compared to solid dams,the grille-dam with material saving and higher stability is used for debris flow disasters mitigation more and more widely.But there is no systematic method for grille-dam design.With reference to the theory for calculating the distance of comb-dam-piers we present ... |
