摘　　要：鸭河口灌区鸭东干渠现状分析与渠道改造提升方案比选,对贯彻落实国家推行现代化灌区改造提升战略部署,切实解决鸭东干渠现状实际问题等都具有十分重要的工程意义。为此,在全面熟悉鸭河口灌区鸭东干渠工程概况的基础上,首先围绕渠身渗流分析及渠身稳定复核等方面实施鸭东干渠现状分析;随之阐述了鸭东干渠改造的必要性,采用钢筋混凝土矩形渠道、混凝土边墙+混凝土底板矩形渠、梯形土渠+混凝土衬砌三种渠道改造方案进行比较,选定合适的改造方案,并从初拟断面尺寸、各方案建设内容和综合分析等方面展开渠身改造提升方案比选;最后优选出鸭东干渠渠身改造提升方案用作桩号1+820~4+348、8+050~8+550段渠道改造提升的典型设计。也可为类似工程实践提供借鉴参考。The analysis of the current situation of Yadong Main Canal in Yahekou irrigation area,as well as the comparison of channel transformation and upgrading scheme,hold significant engineering importance for implementing the national strategic deployment of modernizing irrigation area transformation and upgrading.This will effectively address practical issues associated with the present state of Yadong Main Canal.Therefore,based on the general situation of Yadong Main Canal project in Yahekou irrigation district,the current situation of Yadong Main Canal is analyzed from the aspects of seepage analysis and stability review of the canal.Then,the necessity of the reconstruction of Yadong Main Canal is expounded.Three reconstruction schemes of reinforced concrete rectangular channel,concrete side wall+concrete floor rectangular channel,trapezoidal earth channel+concrete lining are compared.The suitable reconstruction scheme is selected and compared from the aspects of initial section size,construction content and comprehensive analysis.Finally,the reconstruction and upgrading scheme of Yadong Main Canal is selected as the typical design of the upgrading of the channel with pile number 1+820 to 4+348 and 8+050 to 8+550.It can also provide a reference for similar engineering practice.
