Chervinskiy O. Settlements of bored and bored-injection piles from influence of vertical load

This Thesis devoted to development of bored and bored-injection piles settlements method from influence of vertical load. Combined conditional foundation gives ability to avoid defects of existing method of bored and bored-injection piles settlements calculation. Enhanced formulas of additional vertical pressures from regions of conditional foundation basing on formula of R. Mindlin. In developed algorithm of pile settlements calculation considered pile lateral surface in soil, that defined with distribution of holding forces of soil along to lateral surface of pile. Method of modulus deformation Ei adjustment of bottom end of pile is used to take into account pile side face sliding in soil when nonlinear pile settlement is calculating. Results of calculations according to developed method gives good convergence with the results of experimental researches of bored and bored-injection piles settlements on vertical pressing loads influence. Key words: pile setting, stresses, additional vertical stresses, bored piles, bored-injection piles, combined conditional foundation, elastic pile deformation, pile side face compression.
