目的在于通过模型试验总结出电站双孔进水口计算临界淹没水深的经验公式。试验在三峡电站进水口的大比尺模型 (1∶ 30 )上进行。试验数据用计算机进行回归分析 ,拟合出数据曲线 ,得出双孔进水口计算临界淹没水深的经验公式 ,将此公式与清华大学水利系以前做的单孔进水口临界淹没水深经验公式及 Gordon公式进行比较。指出双孔进水口公式具有实际工程用途且具有优越性 ,在设计电站双孔进水口确定临界淹没水深时 ,可供设计者参考
The purpose of this paper is to summarize the empirical formula for calculating the critical submerged water depth through the double-inlet of the power station through model tests. The experiment was carried out on a large scale model (1: 30) of the inlet of the Three Gorges Power Station. The experimental data were analyzed by computer and the data curve was fitted to get the empirical formula of calculating the critical submerged water depth of the double-hole water inlet. This formula was compared with the empirical formula of submerged water depth of the single-hole water inlet made by Tsinghua University and Gordon Formula to compare. It is pointed out that the double-hole water inlet formula has practical engineering application and has advantages. When designing the double-hole water inlet of a power plant to determine the critical submerged water depth, it is available for designers’ reference
