摘　　要：渠道是农田水利最主要的设施之一,其好坏程度关乎到农田灌溉和灌溉水利用率。以辽宁北票万松山村小型农田为例,实施灌溉渠道改造,针对项目区实际情况对渠道灌溉流量、渠道参数进行计算设计,选取断面形式,又针对渠道受冻胀破坏影响采用“置换法处理地基”。同时对改造后效益进行分析,预计每年节水量约7600m^(3),年增产效益3.4416万元。Canal is one of the most important facility of farmland water conservancy,and its quality is related to farmland irrigation and irrigation water utilization rate.Taking the small farmland in wansongshan village,Beipiao,Liaoning Province as an example,this paper implements the reconstruction of irrigation channels,calculates and designs the irrigation flow and channel parameters according to the actual situation of the project area,selects the section form,and adopts at the same time,the benefit after transformation is analyzed.It is estimated that the annual water saving is about 7600m3 and the annual yield increase benefit is 3441600 yuan.
