西霞院水利枢纽输水总干渠设计要点分析OA
Key Design Points of the Main Water Conveyance Canal of the Xixiayuan Water Conservancy Hub
系统总结了西霞院水利枢纽输水总干渠的主要设计要点,包括渠道横断面形式与尺寸确定、边坡衬砌及分缝构造布置,以及基于水力计算确定渠顶高程等关键内容;并选取不利典型断面对渠道进行抗滑与抗渗稳定性分析,以复核设计方案的合理性.在此基础上,通过抗冰冻设计及局部特殊渠段防护措施,进一步提升渠道使用寿命与耐久性.结果表明,所设计断面在不同工况下均满足相关规范要求,可为工程后期安全稳定运行提供保障.研究成果对提升区域水资源配置效率、保障粮食安全以及完善现代水网体系具有重要意义.
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.
