白家河水库溢洪道侧槽水力设计

摘要

Width often determines the reservoir spillway crest elevation.The side channel spillway crest eleva-tion will reduce,but also to reduce the amount of spillway.According to White River Reservoir side channel spillway design and overall arrangement of comparison ,describes side channel spillway of hydraulic calculation contents and step,given the discharge capacity WES weir,weir surface curve,critical depth of chute side end groove depth,groove side elevation and bottom ends of the side grooves water lines,hydraulic calculation methods and results for the white River Reservoir side channel spillway is designed to provided.%溢洪道宽度往往决定着水库坝顶高程。而侧槽式溢洪道既能减少坝顶高程，又能减少溢洪道工程量。根据白家河水库侧槽溢洪道的设计方案比选和总体布置情况，阐述了侧槽溢洪道的水力计算内容及步骤，给出了WES实用堰泄流能力、堰面曲线、泄槽临界水深、侧槽末端水深、侧槽末端底高程和侧槽水面线等水力计算方法和成果，为白家河水库侧槽溢洪道的设计提供了依据。
