摘要
灌溉渠道是农田重要的基础设施，而渠床渗漏是渠系水量损失的主要途径，渠道衬砌可减少渠床渗漏损失，提高灌溉效益。不同的衬砌方案效益各不相同，通过对相同流量、不同断面和不同衬砌方式的渠道进行单价分析，考察较适宜的衬砌方案。结果表明，3种断面中梯形断面渠道单价最低；矩形断面渠道单价次之，U型断面渠道单价最高。5种衬砌方式中，梯形断面边坡预制渠道单价最低，预制U型槽单价最高。
Abstract
Irrigation channel is an important infrastructure of farmland , leakage of canal bed is the main way of water loss , lining can reduce leakage loss and improve irrigation efficiency.By studying irrigation canal unit cost ahout the same discharge with different section and lining fashion, the results showed:in three sections, the trapezoidal cross section irrigation canal unit cost was lowest, the rectangular cross section irri-gation canal took second place, the U-shaped cross section irrigation canal unit cost was highest.Among five lining fashion, the trapezoidal cross section with slope prefabricated irrigation canal unit cost was lowest , the U-shaped cross section with prefabricated irrigation canal unit cost was highest.
