| 摘 要： | 通过水工模型试验研究喜河电站厂房坝段不同围堰拆除高程对坝区水流流态、排沙及冲渣的影响,及在现有水工结构下,通过运行闸门泄洪方式能否做到机组进水口"门前清",论证现状残留围堰的合理性,为喜河水电站提出合理的围堰拆除高程,也为其他类似电站围堰高程提供可借鉴的资料。

| Abstract: | The effects of the upstream cofferdam with different removal elevation on flow regime, sediment discharge, flushing residue for the Xihe Hydropower Station was studied in hydraulic model experiments. The results demonstrate that the discharge gate may operate rationally to realize the inlet of generating units without sediments in the existed conditions of hydraulic structure, and cofferdam removal elevation is reasonable, which may provide reference for other similar hydropower stations. |

| Keywords: | cofferdam removal elevation sediment discharge scouring amount |
