Abstract：This paper systematically summarizes the main design points of the main water conveyance canal of the Xixiayuan Water Conservancy Hub,including the determination of channel cross-sectional form and dimensions,the arrangement of slope lining and jointing structures,and the determination of canal crest elevation based on hydraulic calculations.A typical unfavorable section is selected to carry out anti-sliding and anti-seepage stability analysis of the canal,so as to verify the rationality of the design scheme.On this basis,through anti-freezing design and protective measures for locally special canal sections,the service life and durability of the canal are further improved.The results show that the designed section meets relevant code requirements under different working conditions,which can provide assurance for the safe and stable operation of the project in the later stage.The research results are of great significance for improving regional water resources allocation efficiency,ensuring food security,and perfecting the modern water network system.
