Abstract
In water diversion and supply projects, the water transmission canals mostly are connected to tunnels, underground canals, open tunnels and aqueducts, etc which are discontinuously distributed and form the water transmission structure.The canals are classified in loess soil, rock and sandy gravel&gravel soil, etc in type.Through analysis on local head loss, flow velocity without sediment and seepage loss as well as the hydraulic calculation and determination of the hydraulic factors of the canal practice in loess soil and rock, the design sections and corresponding hydraulic parameter curves are mapped respectively so that the optimum hydraulic section scope is determined, the practical and economic section is selected and designed.This provides the engineering design of water transmission canal with reference.关键词
