摘要
采用三维数值模拟、水力学计算、物理模型试验综合分析的方式研究密云水库第一溢洪道改建工程不同工况下的泄流状况和水力特性,互相校正,优化和验证了设计方案,确定改建方案是保留原闸、施工期原闸用作围堰、在原闸下游建新闸的"双闸方案",提出"双闸+旧闸胸墙拆除+矩形泄槽"为推荐方案,实际效果明显,对类似老闸的改造过程有较好的借鉴意义。
In this paper,three-dimensional numerical simulation,hydraulic calculation and physical model test are used to study the discharge and hydraulic characteristics of the first spillway of Miyun Reservoir under different conditions.In addition,the research has optimized and verified the design scheme,and the actual effect is obvious.It is determined that the rebuilding scheme is the"double gate scheme",that is,the original gate is retained,the original ram is used as cofferdam during construction,and a new gate is built downstream of the original gate.It makes the layout of the project more reasonable,solves the problem of the opposition between flood prevention and construction safety during the reservoir storage and construction,reduces the project cost,and provides the basic data for the project design and operation management.In the future similar to the old sluice renovation process has a better reference.
