文中概述了我国水土资源短缺情况 ,渠道防渗在营造 2 1世纪节水型农业中的作用 ,并在我国实现第三步战略目标的新形势下 ,指出了提高防渗标准的必要性。进而对防渗工程的设计年限、设计指导原则、设计材料、断面和结构形式以及伸缩缝填料等方面 。

In this paper, the situation for lack of soil-water resources in our country and the role of canal seepage control in saving water agriculture in the 21th century are discussed generally. The necessity for raising the standard of seepage control is indicated. A lot of new and suitable measures are put forward for the design period, design principle, design materials, cross section and structural form, and also the expansion joint filler of seepage control works.
