Novytskyi O. The vibroreinforced soil-cement piles made by deep soil mixing method

The object is interaction of soil-cement pile with the soil in the process of compression; goal - to study the bearing capacity of the material soil-cement piles produced by deep soil mixing technology and methods of it's improvement; research methods - experimental, research soil-cement properties; determination of chemical additives; the laboratory modeling of deep soil mixing technology of soil-cement piles; full-scale high-speed poker vibration of pile's material; reinforcing of soil-cement piles; full-scale static testing of pile's bearing capacity; theory: statistical analysis of the results of research; numerical modeling of stress-strain state; calculation of soil-cement piles bearing capacity of the material on the base of calculation of reinforced concrete; novelty: - first significantly increased the carrying capacity of the material soil-cement piles reinforcing by immersion high-dive deep vibrations (the vibroreinforced soil-cement piles); - improved design scheme of the system " the vibroreinforced soil-cement piles - foundation" using the finite element method and elastic model system for evaluation of the stress-strain state; - obtained new experimental data of chemical additives and metal reinforcing fiber for strength soil-cement piles by deep soil mixing method in the laboratory; results - obtained new evidence-based theoretical and experimental results that address scientific and technical problem of increasing the bearing capacity of the material the vibroreinforced soil-cement piles, manufactured by deep soil mixing method whose implementation provides significant economic impact and reduce resource input technologies, scientific value is contribution to Theory and practice of soil mechanics and foundation engineering; industry - construction.
