When designing engineering protection, it is necessary to use modern and progressive technologies. The technical decisions made must comply with the fundamentals of design - economic and operational efficiency. This article discusses the methods and principles of operation necessary for hazard assessment and the development of effective measures to prevent and reduce risks in the design, selection of optimal solutions and recommendations for the development of engineering protection projects. A section of a public highway of local significance in the Krasnodar Territory was selected during the survey. The materials of engineering and geological studies of the slope were used as initial data, which included reconnaissance route observations, engineering and geological workings with soil sampling, and determination of the physico-mechanical characteristics of the soils.

The article is devoted to the reduction of steel consumption in the compressed zone of reinforced concrete elements. Special attention is paid to the combined prestressing, in which the armature of the stretched zone is subjected to prestressing, and compressed – prestressing. The combined prestressing allows to reduce the steel consumption, and also to increase the performance of many technical characteristics by increasing the limit stresses in the high-strength reinforcement of the compressed and stretched zones

Keywords: the combined prestressing, compressed area, consumption of steel compressed fittings
