拱网消力池是一种适用于低佛氏数底流消能的新型悄能工，特别适用于渠系建筑物涵、闸下游的消能防冲上。模型试验和实际工程应用都表明其具有良好的消能防冲特性。影响拱网消力池水力特性的因素很多，除入池水泥的佛氏数、网板的相对位置、网板的相对高度等参数外，网板本身的型形也显著地影响出池水流的水力特性。拱网的几何参数有开孔率、拱形、网孔形状、网板厚度。试对拱网特性进行优化：①开孔率可选取３０％～４５％之间，如无特殊要求宜选４０％；②拱形选择主要考虑实际工程规模，单孔半径不宜超过２．５ｍ；③孔形、孔径、板厚时水力特性影响不大，主要考虑施工和强度条件。
The arch net stilling pool is a new type of migrant worker who is suitable for low-flow dissipation of low Fossil energy. It is especially suitable for energy dissipation and anti-flushing of downstream culverts and sluices of canal systems. Both the model test and practical engineering application show that it has good energy dissipation and anti-corrosion properties. There are many factors that affect the hydraulic characteristics of the energy dissipating pool in the arch net. In addition to the Foil count, the relative position of the screen, the relative height of the screen, etc., the shape of the screen itself also significantly affects the flow of water Hydraulic characteristics. Arch geometric parameters of the hole rate, arch, mesh shape, screen thickness. Try to optimize the characteristics of the arch network: ① The opening rate can be selected between 30% ~ 45%, if no special requirements should be selected 40%; ② arch choice to consider the actual project size, single hole radius should not exceed 2.5m; ③ hole shape, hole diameter, thickness of the hydraulic characteristics of small, mainly consider the construction and strength conditions.
