Математичне моделювання роботи комплексного стовпчастого пальового фундаменту

Abstract

In this work, it is proposed to use the idea of a complex foundation, which is used for slab grids, for a columnar pile foundation. In mass design, having determined the required number of piles, based only on their bearing capacity, they try to place them in the bushes as compactly as possible in order to reduce the costs of the grid, the work of which is not taken into account. If you place the piles at a considerable distance from each other or place them compactly under the column, but take the dimensions of the grid fairly large, this can compensate for the small number of piles by including the grid in operation.Mathematical modeling of the operation of the pile foundation was carried out using the SOFiSTiK software complex. A study of the implementation of the work of the pile foundation with a soil foundation, depending on the grid size, length, number, placement of piles in the grid, and soil conditions, was carried out. The research examines the homogeneous sandy and clay soil of the base. It is shown that in the case of the use of complex pile foundations with sparse placement of piles and an increased grid area, the efficiency of the foundation as a whole, as well as its individual elements, increases. In order to save materials, it is possible to reduce the number of piles in a group while increasing the size of the grid without losing the load-bearing capacity of the foundation.
