Pidlutskiy V. Interaction base plate with piles of different lengths with a layered soil foundation

The object of study - nature of redistribution efforts to pile work together elements of "basement-foundation-aerial construction" with different length of piles and their rational arrangement in the basement.. Purpose of the study - pile foundations of high-rise buildings. Purpose - to develop a methodology for calculating the pile foundations of high-rise buildings based on the numerical simulation of the stress-strain state of elements of the "basement - foundation - aerial construction" in rational arrangement of piles of different lengths with regard to stiffness and weight of aboveground aerial and foundation construction and soil conditions. Methods: engineering methods for determining the loads on piles of high-rise buildings, the numerical simulation of the stress-strain state of the "basement - foundation - aerial construction" finite element method, tool monitoring deformations of bearing structures of high-rise buildings on the experimental sites. Novelty - first established that the arrangement of the foundations of short peripheral piles reduces the maximum effort in foundation construction as opposed to piles version of the same length or shorter in the central zone, the technique of numerical simulation of the stress-strain state of bases and foundations of high-rise buildings, which allows efficient locate and assign the required length of piles in specific areas with regard to the centers of gravity above ground and foundation structures and their hardness; stiffness and the effects of aerial construction and boundary conditions on redistribution efforts in foundation construction for the design and choice of rational calculation schemes for the design of high-rise buildings, developed principle of separation foundations of high-rise buildings on pile base and pile foundation defined dimensions piles and grillage, which leads to character deformations basis. Industry - construction.
