Abstract. The article deals with the experience of applying lime marl in the formation of engineering protection embankments on the unique territory of the Imereti Lowlands in terms of its engineering and geological conditions. It is known that this site became a place for construction of various facilities for carrying out a wide complex of sports actions of the Olympic Games-2014 (coastal cluster). It is shown how under complex engineering and geological conditions, engineering protection measures were realized. On the support sites - an experiment on the use of local carbonate material for backfilling of soil embankments of engineering protection was executed. Three versions of the backfilling of carbonate soil were used. It is established that the crushed stone mixture of lime marl in the course of 1-2 years of operation of the engineering protection structure increased the parameters of its mechanical properties due to natural cementing ability. In the case where the crushed stone mixture of lime marl was above the groundwater level, calcium oxide contributed to the strengthening of the rock, releasing the cementing layers of the compound. This confirmed the opening of the contact of the underlying soils and soils of engineering protection, as well as the absence of surface deformation in these areas during the operation of the erected structures. In the areas of quarters where the crushed stone mixture of lime marl was flooded as a result of malfunctions of the drainage system, surface settlements and deformations of the structures occurred.
Key words: lime marl, soil mound, complex engineering and geological conditions, engineering protection, consolidation, Imereti Lowlands. - REFERENCES
