摘要
高拱坝泄洪消能设施的选择与布置设计是高拱坝设计成败的关键.姚家平水利枢纽属于典型的高山峡谷地区高拱坝项目,其所在位置特殊的地形地质条件给该高拱坝的消能设施布置与设计造成了一定的难度.通过类似工程的类比分析,并结合相关的模型试验科研,得出了符合本工程特点的泄洪消能设施布置方案,明确了水垫塘的长度、厚度和与之对应的二道坝高度,可供类似工程设计参考.
Abstract
The selection and layout design of the flood discharge and energy dissipation facilities for high arch dams are the key part of the dam design.Yaojiaping Water Conservancy Project is a typical high arch dam project in mountainous and canyon areas.Its unique topographic and geological conditions pose certain difficulties to the layout and design of the energy dissipation facilities.Through analogic analysis of similar projects and relevant model experimental studies,a lay-out plan of the flood discharge and energy dissipation facilities suitable for the characteristics of the project is presented.The length,thickness and corresponding height of the subsidiary dam of the plunge pool are determined.The results can be useful reference for similar projects.
