DETERMINATION OF RATIONAL PARAMETERS OF SUPPORTING STRUCTURES MADE OF SOIL-CEMENT PILES ON LANDSLIDE-PRONE SLOPES

Purpose. The article proposes a method for determining the rational parameters of supporting structures made soil-cement piles on landslide-prone slopes. Methodology. To achieve this purpose, authors performed comparative calculations finite-element models layered slope with arrangement piles: vertical, located at an angle to vertical axis, combined concrete grillage, without different diameters, distances between piles, but same length, which is justified by location determined preliminary sliding surface. Findings. According results calculating contact problem interaction soil mass and structure, regularities formation strength stability reinforced were obtained, makes it possible predict its geomechanical depending surface curve. increasing coefficient variation pile structure substantiated. Numerical substantiate – length their diameter, distance inclination feasibility combining grillage. Originality. For first time, strengthening slopes are dependences changes in absolute displacements, relative deformations, coefficients strength, stability, as well Mises stresses elements inclination, presence grillage that joins them. Methods assessing predicting landslide danger further developed, allowed structure. based complex mathematical centrifugal modeling using real landslides similarity criteria Practical value. have developed patented help perpendicular movement vector body.
