摘要

FIELD: construction. ^ SUBSTANCE: invention can be used for protection of fresh groundwater, ground and soils from pollution by toxic and radioactive substances in areas of technical wastes storage. In expected place of landfill it is created barrier, formed samples set of ground strata for depth till first water-bearing stratum of protected territory and set of local clay samples from the nearest region. Samples of ground strata are divided into layers presented by different lithological members and then territory is divided into separated sections and for each of them functioning critical time as natural geochemical barrier is defined. Then territorial sections (k) are defined, for them variation range DeltaTs of territory required operation life Toper from critical time of its operating as natural geochemical barrier Ts crit exceed previously agreed acceptable value DeltaTs= Toper - Ts crit > Tacc. Then it is formed database of potential contaminant migratory parameters for local clays and materials for artificial barriers, each section of being protected territory is covered by barrier material. ^ EFFECT: providing criterion of predictability territory operation critical time, appraisal ability of contaminants migration velocity in ground strata and increasing of being protected territory operating time. ^ 7 cl, 2 dwg
