主要论述三峡工程电站进水口的型式及其实验结果 .三峡电站进水口设计是有两种型式 ,即单孔方案和双孔方案 ,每种方案都经过数次体型优化 ,并对每种优化方案进行了模型试验 .本文根据试验成果对单、双孔进水口各方案的水力特性进行了综合评述及对比分析 ,最终得出 ,双孔方案总比单孔方案的流态更好 .在给定的控制条件下 ,双孔方案进水前不会导致任何的漩涡产生 ,相反 ,在单孔方案进水口前出现了挟气漩涡 .尽管这处漩涡在单四方案中可以被消除 ,但是要设置破选措施 .试验结果表明 ,双孔方案增大了电站进水口的面积 ,但是并没有降低水头损失 ,两种进口方案有着几乎相同的水头损失 ,但就某种方案而言 ,优化过程还是降低了水头损失的 .本文最后简要评价了 ASCE的设计准则 Mainly discusses the Three Gorges Project power station inlet type and its experimental results.Through the Three Gorges power station inlet design are two types, namely single-hole program and double-hole program, each program after several body shape optimization, and for each optimization program The model test is carried out.This paper makes a comprehensive review and comparative analysis of the hydraulic characteristics of the schemes of single and double inlet according to the test results and finally concludes that the dual-well scheme is better than the single-hole scheme in a given Of the control conditions, the two-hole program before the water does not cause any vortex generation, on the contrary, the single-hole solution in front of the entrapment swirling vortex occurs Although the whirlpool in the single four programs can be eliminated, but to set The results of the tests show that the two-hole scheme increases the area of ​​the inlet of the power plant but does not reduce the head loss and the two inlet schemes have almost the same head loss, but the optimization process is still lower for some schemes The loss of the head.At the end of this paper, a brief evaluation of the ASCE design guidelines
