ABSTRACT
Hosting the Winter Olympics 2014 became an incentive for an active development of the Sochi mountain cluster (Krasnodar Region, Russia). A set of engineering protection measures against dangerous geological phenomena and processes was taken on the territory where sports and recreational infrastructural facilities were to be constructed. The Sochi mountain cluster became a real testing ground for implementing advanced technical solutions in the area of engineering protection in really specific conditions when developing facilities in the national park on a steeply sloping terrain under the risk of high seismic activity (9 points). The article provides review of the measures taken. They include constructing flexible mudflow-retaining and snow-retaining barriers, ensuring the stability of slopes by soil nailing using the GEOIZOL-MP multifunctional geotechnical system, constructing retaining structures (retaining walls) of various designs: piled, corner monolithic on a piled base, reinforced soil, gabions.
