大河水库除险加固设计中的溢洪道设计

Spillway Design of Qahe Reservoir Risk Removal Reinforcement Design

泄水建筑物在水库枢纽中的主要作用是确保大坝及其他挡水建筑物的安全,限制库水位不超过规定的高程,避免上游库区造成过大的淹没损失。因此,溢流坝的设计是水库枢纽设计中最重要的设计之一。本文主要阐述大连市大河水库除险加固设计中溢洪道设计要点及步骤,通过堰型选择、泄水渠水力计算及消能工设计,对溢洪道设计的过程和特点进行相关分析,对相关工程设计有一定借鉴意见。

Sluice structure is mainly used for ensuring safety of dam and other water retaining buildings in reservoir outlet,limiting that reservoir water level does not exceed the specified height,and avoiding large flooding loss on upstream reservoir area. Therefore,overflow dam design is one of the most important contents in reservoir hug design. In the paper,spillway design keys and steps of Dahe reservoir risk removal reinforcement design in Dalian are mainly described. The process and features of spillway design are analyzed through cofferdam model selection, sluice channel water force calculation and energy dissipation design,which provide certain reference significance for related project design.
