渠道防渗 减少渠道输水渗漏损失的工程措施。渠道防渗不仅能节约灌溉用水，而且能降低地下水位，防止土壤次生盐碱化；防止渠道的冲淤和坍塌，加快流速提高输水能力，减小渠道断面和建筑物尺寸；节省占地，减少工程费用和维修管理费用等。 渠道防渗方法可分两类。①改变原渠床土壤渗透性能，又可分为物理机械法和化学法。前者是通过减少土壤空隙达到减少渗漏的目的，可用压实、淤淀、抹光等；后者是掺入化学材料以增强渠床土壤的不透水性。②设置防渗层,即进行渠道衬砌(见彩图),可用混凝土和钢筋混凝土、塑料薄膜、砌石、砌砖、沥青、三合土、水泥土和粘土等各种不同材料衬砌渠床。采用防渗措施后,渠道渗漏损失可以减少50％～90％。混凝土衬砌是一种较普遍的渠道防渗形式，防渗防冲效果好、耐久，但投资较大。塑料薄膜防渗国外在20世纪40年代已开始应用,中国60年代以来发展很快,防渗效果好，造价亦较低，一般应用于流速小的渠道。三合土、水泥土等防渗材料可就地取材，造价较低，适于无冻害地区使用。70年代以来，对沥青玻璃纤维等防渗新材料以及机械化施工等方面的研究、推广应用，正逐步得到发展。在有冻害地区进行渠道衬砌，需采取防冻措施。防治渠道冻胀破坏可采用改善土壤性质和减少土壤水分，减轻基本冻胀强度，使衬砌结构适应基土的冻胀变形等方法。 渠道防渗是农业节水的重要措施之一，正日益受到重视。
