摘要
金村水库为景宁县城区供水主水源,坝高超过90m,泄洪水头差大,现状地形复杂,同时坝址处山谷狭长,属于典型的“峡谷型”水库。本文通过室内模型试验,对“L”形和“I”形侧槽式溢洪道的泄流能力、水流流态、掺气减蚀、挑流消能等方面进行研究,同时结合数值模型分析,对原方案进行改进优化,提出适合本工程的最佳溢洪道布置方案和消能方式,为工程实施提供了依据。
Jincun Reservoir is the main source of water supply in Jingning County.The height of the dam is more than 90m,and the head of flood discharge is quite different.The current landform is complicated.Meanwhile,the dam site is located in the long valley.The reservoir belongs to a typical“valley”reservoir.The discharge capacity,the flow regime,aeration corrosion reduction,deflecting flow energy dissipation and other aspects of the“L”-shaped and“I”-shaped side channel spillways are studied through the indoor model test in the paper.Meanwhile,numerical model analysis is combined to optimize and improve the original plan.The optimal spillway layout plan and energy dissipation mode to the project are proposed,thereby providing basis for the project implementation.
