Zagoruyko E. Enhancing the stability of slopes in weak arrays grouting system elements

In the thesis the theoretical framework of enhanced stability margin slopes through the introduction of sliding zone elements with greater structural strength vykonnanyh using jet grouting technology "Jet-grouting", determine their geometric and strength parameters and effects on the stress-strain state of soil foundation. Theoretical and numerical modeling of the stress-strain state of the soil solid landslip areas revealed that the phased arrangement of elements in the zone of plastic deformation can manage its development and influence the overall stability of the slope. Put formula for determining the geometrical parameters hruntotsementnyh elements and their number for the location in a zone of plastic deformation landslip slope. Found that the coefficient of stability margin depends on the particle hruntotsementnyh elements in the zone of plastic deformation. Having stronger structural elements in the area with more values ?, s, and module common strain causes the increasing importance of the structural strength of the entire array. The findings of laboratory studies confirm the fact of increasing strength and deformation characteristics of structural reinforced soil mass or "heokompozytu 'values are saturated with increase in 2-4 times filtration rate does not change, only when injected bentonite clay its value significantly decreased to 0.004 m / day, which is almost 8 times. It should be noted a significant increase in the angle of internal friction almost doubled and a significant increase of 4.0...4.5 times the specific adhesion to saturated soils. The results in the study of the effect hruntotsementnyh elements to form VAT slope provide an opportunity to identify the most efficient discrete zones of their location in the body slope and time to develop engineering protection landslip area. Keywords: landslide, stability of slopes, the zone of plastic deformation, jet grouting, the safety factor of stability, the calculation parameters.
