Abstract
It is known that the stress values and the distribution of the latter in depth depend to a large extent on the size of the Foundation sole and especially the width. In this article, in order to select the optimal width of the Foundation sole and the thickness of the sand cushion, the influence of the sole width on the distribution of vertical stresses in the ground base is studied on the example of foundations for metal pipes. The presence of weak water-saturated clay soils within the construction site was taken into account. Variants of the device from traditional prismatic piles and foundations of small laying on a sandy pillow are offered. a technical and economic comparison of options was carried out. The advantages and disadvantages of each option are analyzed. Using the methodology of verification calculations in the design of sandbags, the optimization of the accepted version of the foundations was made.

Summary
Аннотация Известно, что значения напряжений и распределение последних по глубине в значительной мере зависят от размеров подошвы фундамента и особенно ширины. В статье с целью выбора оптимальной ширины подошвы фундамента и толщины песчаной подушки исследуется влияние ширины подошвы на характер распределения вертикальных напряжений в грунтовом основании на примере фундаментов под металлические трубы. Предложены варианты устройства из традиционных призматических свай и фундаментов мелкого заложения на песчаной подушке. Используя методологию поверочных расчетов при проектировании песчаных подушек произведена оптимизация принятого варианта фундаментов.
