本文简述了运城地区渠道防渗发展概况，对几种防渗结构形式进行了评价，并对渠道防渗效果和经济效益作了分析，为了更显著地提高防渗和抗冻胀效果，作者推荐应采用混凝土复合防渗和现浇Ｕ型渠防渗形式，即：在预制板和现浇混凝土两种防渗体渠道均采用板下再铺设一层玻璃丝防渗布的复合防渗形式。这种新型防渗结构形式很有发展前途，而且必将在渠道防渗领域占主导地位的新型防渗结构形式。 This article briefly introduces the general situation of canal seepage prevention in Yuncheng area, evaluates several types of seepage control structures, and analyzes the seepage control effect and economic benefit of the canal. In order to improve the anti-seepage and anti-frost heaving effects obviously, It is recommended that concrete composite seepage control and cast-in-place U-shaped canal seepage prevention mode be adopted, that is, the composite seepage control mode with glass wool impermeable cloth shall be laid under both the precast slab and cast-in-place concrete impervious channels. This new type of impermeable structure is very promising and will surely be in the form of a new type of impermeable structure that will dominate the field of canal seepage prevention.
