Petrash O. Soil-cement piles, manufactured by deep soil mixing technology

Object - collaboration of components of the system "reinforced soil-cement pile - basis"; purpose - researching of functioning of reinforced soil-cement pile, manufactured by deep soil mixing technology, definition of calculation methods of bearing capacity of these piles on material and soil; methods - definition of soil characteristics of which the reinforced soil-cement boring pile was made, definition of physical and mechanical characteristics of soil-cement manufactured in field and laboratory conditions, research of bearing capacity of the pile in field conditions, numerical modeling of stress-strain state of the system "soil-cement pile - basis" using finite element method, statistical analysis of research results; novelty - for the first time it was established influence of reinforcing with steel bars to the strength of soil-cement pile on material, thus, it was experimentally proved that strength of the pile on material significantly rises due to the rising of reinforcing percent, it was improved the technique of making up settlement schemes for the modeling stress-strain state of reinforced soil-cement piles using finite element modeling, it was for the first time proved methodic of obtaining deformation diagram of soil-cement, from which the strength and deformation characteristics of soil-cement were obtained; results - functioning of reinforced soil-cement boring pile was researched and methods of calculations of its bearing capacity onmaterial and soil were defind, industry - building
