Description
Expansion and increasing of the Krasnodar region transport infrastructure during the construction of the Olympic facilities together with the new land development created a necessity for construction in the remote areas of landslide slopes with the complex engineering-geological conditions. Constructions of bored piles, jammed by in nondisplaceable soil are often used as one of the measures for the protection of surface rocks landslide movement and tightening the slope weak sections. Such constructive solution is often being considered the best, and sometimes the only acceptable solution. When designing engineering protection it is recommended to consider the use of a number of active protection activities, aimed at the landslide processes stabilization. However, in case of construction production impossibility due to terms of organization, it is necessary to provide passive protection which would secure that the landslide streamlines the construction. Currently, the mechanism of the soil landslides interaction with constructions of detached objects spot protection isn’t studied enough. Known methods adopt simplifications and assumptions which lead to definite significant errors in the design of slope protection structures. Security and reliability of such structures can only be achieved with the adoption of high factor of safety values. This leads to increased material consumption and labor input for the erection of defensive structures also reduces the economic efficiency of these structures. In addition the process of designing protective structures in the Krasnodar region is further complicated by fact that the landslide of construction area is mainly folded by flowing clay soils
