Carbonaceous breeds as the material of engineering protection of Imeretinskaya valley (Sochi)

The experience of the use of carbonaceous breeds during the formation of the engineering protection embankments, in the territory of Imeretinskaya Valley is considered in the article. It is demonstrated how the measures of the engineering protection were held in the difficult engineering-and-geological conditions. The experiment on the use of local carbonaceous material took place on certain quarters, because of the lack of volumes of material of the embankment of the engineering protection. The soils of the Kamensk limestone quarry were used, different options of dumping of the carbonaceous soil were applied. It is proved that crushed-stone mix from carbonaceous material raises the indicators of the mechanical characteristics due to the natural cementing ability. In case when crushed-stone mix of lime marl was higher than the ground water level, calcium oxide promoted strengthening of the breed, allocating the connections, cementing the layers. There were the surface sediment and the deformation of structures in the sites, where crushed-stone mix of carbonaceous structure was waterlogged. The increase in the durability of soils of dumping because of the formation of the monolithic plate in the embankment basis from carbonaceous breeds can be used when carrying out engineering protection in the similar engineering-and-geological conditions.
