大流量水电站的消能设计历来都是非常复杂和困难的.在1:60溢流坝表、中泄水孔断面模型上对密松水电站泄水建筑物的布置方案进行了泄流能力、流速流态、压力分布等相关水力学问题的试验研究,并通过10多个方案的比较优化,提出了基本可行的泄水建筑物体型和消力池型式.研究成果表明:表孔取消宽尾墩,采用跌坎式消力池方案,可有效降低底流消能时的池底板流速,同时消除宽尾墩形成的水翅击打两侧导墙现象,达到了较满意的消能效果.试验成果对该工程设计提供了较好的参考方案,并对类似工程有很好的启发借鉴作用.
The energy dissipation design of large-flow hydropower stations has always been very complicated and difficult.In the 1:60 overflow dam table, in the middle of the spillway cross-section model of the discharge layout of Myitsone hydropower station discharge capacity, flow rate Flow pattern, pressure distribution and other related hydraulics problems, and through comparison and optimization of more than 10 schemes, put forward the basic feasible drainage body type and stilling pool type.The results show that: , The use of drop-sink power pool program, can effectively reduce the bottom flow when the pool floor energy dissipation, while eliminating the formation of the tail pier flaps on both sides of the guide wall phenomenon, to achieve a more satisfactory energy dissipation effect. This project provides a good reference design, and a good example for similar projects inspired by.
