Balakshin O. Bearing capacity of jacked-in piles with enlargements on the side

Dissertation work is sanctified to research of bearing strength of the pressed piles with lay-by on a side, and to the search of methodology of determination of bearing strength of such piles on soil. The scale and model tests of work of piles are conducted, the numerical design of the tensely-deformed state is executed in soil round a pile by the method of eventual elements. The "method of account of lay-by" is worked out for determination of bearing strength of the pressed piles with lay-by. The fundamental variants of calculation charts of pile are offered with one and two lay-by, and algorithm of determination of bearing strength of such piles. Keywords: the pressed pile, pile with lay-by, bearing strength of pile, laboratory research, design, model tests, close-settled zone.
