摘要
模型相似性论证是特大型水利枢纽整体水工模型试验研究中的重要内容之一,由于长洲水利枢纽河势受上、下游边界条件的约束,要求整体正态模型的范围很大,因此需对模型进行相似性的论证,即比对原型实测的水位、流速大小及分布、三江流量分流实测资料等,检验模型与原型河道的相似性,确保模型试验的精度。
Similarity demonstration is one of the most important parts of integral hydraulic model test. The constraint on hydraulic complex by boundary conditions in upper and lower reaches requires a large area for the normal model, hence the similarity demonstration is necessary. In other words, to prove the similarity of the model with the actual river channel so as to ensure an accuracy in model test from the aspects of actual measured water level, flow rate and its distribution, and the observed data on diversion ratio, etc.
