多沙河流引水工程泄洪闸消能防冲效果对比分析

Comparative Analysis on Energy Dissipation and Erosion Control Effect of Flood Discharge Gate of Sediment-laden River Diversion Project

通过模型试验对泄洪闸下游四面体散块、四面体相互连接成整体、四面体消能段不同布置形式以及消力池消能方案进行了试验比较,对弯道段铅丝笼防护、块石防护、扩宽左岸导流堤、弯道设置丁坝等方案进行了比较试验,提出了泄洪闸下游的消能形式和上游挡水墙、右岸山体及下游弯道最佳的防护方案等建议。

Based on the model test,this paper makes comparison of the tetrahedral bulk blocks,tetrahedrons as a whole,different layout of tetrahedral energy dissipation section and different energy dissipation schemes of stilling basin in the downstream of the flood discharge gate,carries out the comparative tests on the protection of the galvanized wire gabion in the curved section,the protection of the block stone the expansion of the diversion dike in left bank,and the setting of the spur dike in the bend,as well as proposes suggestions such as the energy dissipation form in the downstream of the flood discharge gate and the optimal protection scheme for the upstream retaining wall,the right bank and the downstream bend.
