巨石在堰塞湖泄流过程中的影响试验分析

Analysis for the impact of Boulders in Yansai lake discharge

汶川大地震后,在唐家山堰塞湖泄流槽内和稳定的下游河道上,存在很多巨大的石头。这些巨石的存在到底对泄流过程起到怎样的影响,为探索其中的规律,本文设计堰塞湖的泄流试验,通过量测添加巨石情况下河道坡度以及河道地形与无巨石情况下比较,探索巨石对泄流过程造成的影响。

After the earthquake happened in Wenchuan, there are many boulders left in river channel and discharge chute downstream of Yansai Lake of Tangjiashan. The existence of these boulders in the end of the play what kind of impact the process of discharge, in order to probe the laws, this paper according to the Yansai lake discharge experiment with boulders and without, and measured the river channel slopes and terrains, and compared them and explored the impact of boulders.
