摘　　要：拱型网板(简称拱网)是设置在消力池里的辅助消能工,它具有良好的水力特性和消能效果,模型试验和原型观测结果表明,消力池中设置拱网可大大降低消力池的规模和工程费用。研究了影响拱网水力特性的几个参数和拱网的消能率。基于模型试验和原型观测结果,给出了确定网高和网距的经验公式。经几个工程应用结果表明,经验公式与实际是相符的。Arch network floor is a kind of auxiliary energy dissipater in stilling basin. It has excellent hydraulic property and effect of energy dissipation. The results of model test and engineering observation show that arch network floor can decrease the length of stilling basin and cost of the project. In this paper, several parameters; which affect hydraulic property of arch network, and the efficiency of energy dissipation, are researched. The empirical formulae of the network height and interval distance are provided according to the results of modeling test and engineering observation.
