摘要
为验证河口村水库导流洞布置方案的合理性和优化的可能性,根据重力相似准则,采用比尺1∶40的单体正态模型系统研究了导流洞泄流能力、水流流态及明满流界限、压力分布、进出口体型、消能防冲等,尝试采用不同进口形式来消除进口漩涡,并提出有利于消能防冲的出口形式。对比试验结果表明,在进水口前布置V型消涡梁可很好地消除进口漩涡,同时在导流洞出口布设钢筋笼防护,可有效抑制冲坑的进一步发展。
In order to verify the design layout rationality of diversion tunnel of Hekou village reservoir and possible optimization, based on the principle of gravity similarity, the scale 1 ： 40 normal single model is used to study the dis- charge capacity of the diversion tunnel, flow pattern and full flow boundary, pressure distribution, inlet and outlet size, energy dissipation and erosion control, And then different inlet form is applied to eliminate inlet vortex. Finally, the out- let form for energy dissipation and erosion control is put forward. Compared with test results, it shows that the V-type eddy-eliminating beam arranged in front of the inlet can effectively eliminate inlet vortex; arrangement of reinforcement cage protection in outlet of diversion tunnel can effectively inhibit further development of scour hole.
