Golovko A. Heels of foundations with the circular form of sole on the saturated water ground layer of eventual thickness

Object of the research system satured and nonsatured soil layer of finite thickness, which tends to eccentrically loaded ring foundation with the sole form relationships with various internal and external radii and thick foundations. The aim of the thesis is to develop calculation formulas and tables for determining current and stabilized roll foundation with ring shape sole design scheme in the finite layer thickness. Methods experimental method used in determining the standard and rheological properties of soil and deformations of the foundations of the model foundation ring at the sole form of layers of different thickness and radius ratio; theoretical methods aimed at establishing patterns of development in time eccentrically roll-ring loaded the bases for water-sated soil layer of finite thickness, which has the properties of creep, analytical and numerical methods for solving model problems. Theoretical and practical results of practical recommendations to calculate the stress - strain state of "water-sated soil layer of finite thickness - the foundation of the ring form a sole" taking into account creep of the soil skeleton, textural characteristics of soil depth (depth of discontinuity) on the interval of time. The technique implemented in the development of applications and package tables. Scientific novelty: an algorithm for determining roll- eccentrically loaded the bases with the ring form the sole basis of the model as a linear elastic medium, in the model of isotropic elastic water-sated bases and assessed the development roll in time (these results are generalized to the case of water-sated base) and water-sated for no basis, that tends to creep settlement schemes of finite layer thickness and absolutely solid foundation (first received);The relationships of the development in time eccentrically roll-ring loaded the bases with a sole form of water-sated sandy and clay soil layer of finite thickness that has creep properties (returned first);received further development of the boundary element method that allows to determine the stress-strain behavior of soil under the foundations of a model water-sated creeping linear isotropic medium. Degree of implementation: obtained theoretical solutions used JSC «Ukrspetsstroybureniye» heel in calculating chimney in Nikopol and for calculation and correction of roll water tower in Mena, Chernihiv region. At the design stage methodology used in determining roll LTD «ARHSTROYPROEKT» for calculating the sample base with the ring form of sole. Field of use: design and operation of buildings.
