某干渠现状分析与改造提升方案比选OA

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.
