Abstract

The article presents the results of laboratory studies of the filtration properties of fine-grained components of soil mixtures used in the construction of earthen hydraulic structures. Laboratory tests of six groups of samples with particle sizes up to 5 mm and different weight fraction contents were carried out. The influence of the weight amount and particle sizes of various fractions of fine earth on the rate and volume of water filtration through the samples has been studied. It is shown that the dependence of lowering the water level on the filtration time is linear and depends on the characteristics of the fine-earth fractions. For large fractions (5-2 mm m 2-1 mm in size), the filtration rate is influenced primarily by the weight content, while for small fractions (less than 1 mm), particle sizes play an important role.
