农业综合开发项目灌排水渠道水力断面有关参数的确定与探讨

无论是中低产田改造项目还是山区小流域治理项目的施工设计阶段，均不可避免的涉及到灌排水渠道的纵横断面设计，而灌排水渠道横断面设计则主要通过渠道水力断面计算确定水力最佳断面结构型式，并分析如何由已确定的水力最佳断面相关参数进一步确定实用经济断面构型式。工程设计中渠道断面结构型式多样，用到的参考资料涉及范围广，因此．有必要对渠道水力断面公式在农业综合开发项目中的设计与应用进行归纳和探索。

tem of comprehensive Agriculture Exploitation to infuse catchment outlet water power a cross section concerning the parameter really settle with study

Regardless is medium low produce the farmland reformation an item still a mountain area small river valley to manage item of construction design stage, all ineluctable involve to infuse to drain the cross section design of the maneuver of outlet, but infuse catchment outlet cross section to design to then mainly pass the assurance water power of the cross section calculation of the outlet water power the best cross section structure pattern, and analyze how the water power best cross section related parameter make sure by already makes sure practical economic cross section Gou pattern further. The structure pattern of the outlet cross section is diverse in the engineering design, the reference for use involves scope widely, therefore, have a necessity to the cross section formula of the outlet water power in the agriculture comprehensively the development the item of the design and the application carry on induce with investigate.
