蹉动式综合消能技术在大江水库溢洪道消能中的应用

Application of the differential typed synthetic dissipation technique in spillway project of the Dajiang reservoir

大江水库溢洪道为开敞式溢流宽顶堰型 ,由于洪水冲刷等影响 ,溢洪道及其下游遭受不同程度的破坏 ,危及工程安全 ;在工程除险加固中 ,经试验分析后采用蹉动式消力墩与消力池结合方案 。

The spillway project of the Dajiang reservoir is open broad crested weir. Because of the scour influence by the flood, the spillway and its upper reaches were destroyed in various degrees and influence the project security. The differential typed synthetic dissipation technique was applied in spillway project strengthening and eliminating dangers and the dissipation effect was remarkable
