Tytko O. The Major factors of work of the bases from group of piles at action of vertical loadings

The dissertation is devoted to questions of search of optimum parameters bases from group of piles. The experimental researches bases from piles establish, that bearing ability bases from piles of different length (short and long) approximately identical with bearing ability bases from piles of equal length (long piles). It has allowed to develop new rational models of the bases from group of piles of different length, thus the economic benefit on expenses of a material and power resources is received at the device of the given types bases from piles. The character of distribution of efforts between piles of a bush and influence them on bearing ability of the bases from piles is established. The new technique of planning of experimental researches piles groups of the bases on many factors to parameters is offered. The new methods of account of the characteristics is intense - is deformed statuses of a ground about piles space with use of numerical methods and mathematical models are developed. The comparisons of the received results with the data of other researchers. The recommendations for introduction of researches in practice of construction are given. Keywords: group of piles, bearing ability, basis, numerical methods, mathematical model.
