在堤、坝建筑中已越来越多地采用薄的、大多数是所谓的人工防渗体。鉴于这种防渗体有许多特点,所以提出了小裂缝对防渗体效用的影响问题。这种裂缝既会造成渗漏损失,又会造成坝的渗流。本文将对此问题的某些情况作进一步定量研究。 In the dike, dam construction has been increasingly used thin, most of the so-called artificial seepage control body. In view of the many features of this seepage control body, the question of the effect of small cracks on the effectiveness of the seepage control body is proposed. Such cracks will not only cause leakage loss, but also cause dam seepage. This article will do some further quantitative research on some of the problems.
