| 摘 要： | 目前,弧形闸门的水力计算方法主要基于能量方程或量纲分析,无论哪种方法,其中都包含有与模型试验或原型数据有关的经验公式或常数系数,因此所得公式通常仅适用于某范围内,在实际应用时,有时会带来较大的误差,给弧形闸门的水力计算、闸门校准等工程应用带来诸多不便.通过弧形闸门的实验室水槽数据和现场观测数据,将传统的基于能量方程的方法和量纲分析的表征方法进行了比较,在分析了不同方法的特点的同时,指出不同方法的应用条件,为闸门水力计算和校准等计算方法的选择提供了依据.

| Abstract: | At present the hydraulic calculation methods of radial gates are mostly based on energy equation or dimensional analysis. These methods include empirical formulas or constant coefficients,which should be calibrated by experimental data or field data. These discharge formulas of radial gates could usually be used in some situation. In other situation,the calculated discharge may have produce large error,which makes trouble to method selection of radial gates hydraulic calculation or calibration. In this pape... |
