ANALYSIS OF TEST RESULTS OF THE ENBANKMENT REINFORCEMENT WITH REINFORCED SOIL-CEMENT PILES

Purpose. The purpose of the work is to analyze results test embankment reinforcement with reinforced soil-cement piles. Methodology. An analysis ground situation was carried out definition modern trends in use geosynthetic materials and algorithm for strengthening piles using a special square bit has been developed implemented practice. load-bearing capacity determined by reasoned selection structure, soil base, material, depth pile laying accordance engineering geological conditions, structural scheme building method their arrangement. Findings. 6 length 21 m 23 were tested. During manufacture Nos. 1, 4 6, which 22...23 m, during drilling it found that massive monolithic granite lies at base (the sunk 0.5 m), presence cracks not fixed. Piles 2, 3, 5 had cracked granites as they also deepened m. For these piles, values vertical displacements its loading unloading stages obtained. calculated pressing load on tested ranges from 268.3 t·s 275.0 t·s. Originality. It consists obtaining dependences settlements created basis jet mixing technology, testing modes. Practical value. changing stiffness embankment, since elements can be manufactured deformation modulus 300...600 MPa, problem solved. Practically, possible reduce difference artificial structure track superstructure, will allow eliminating ballast recesses.
