Study of Optimal Area Array of Double Gate Shafts of Asymmetric Water Diversion System

针对不对称引水系统双闸门井最优面积组合选择的问题,基于不对称双闸门井涌波波幅计算式,采用无量纲参数,研究了不对称引水系统中双闸门井最优面积组合的影响因素和计算方法,揭示了不对称引水系统中双闸门井涌波波幅与闸门井面积组合的非线性关系。依据双闸门井的最高涌波值基本一致的原则,得出了不对称引水系统双闸门井最优面积组合值,并根据该值与岔管位置的关系得出了不对称双闸门井最优面积组合值的回归计算式,为不对称双闸门井的面积组合设计提供了理论依据。

Aiming at selecting the optimal area array of double gate shafts of asymmetric water diversion system,this paper,by adopting dimensionless parameter,researched on the influencing factors and calculation methods of optimal area array of double gate shafts of asymmetric water diversion system based on the equation of wave amplitude of double gate shafts.The result reveals the nonlinear relationship between the wave amplitude of double gate shafts and the area array of gate shafts.According to the principle that the wave amplitude of double gate shafts is basically identical,the paper also obtains the value of optimal area array of double gate shafts.Finally,giving the relationship between the value and the position of bifurcated pipe,it obtains regression equation of the optimal area array of double gate shafts,which can provide theoretical basis for the design of area array of double gate shafts in the asymmetric water diversion system.
