Mosicheva I. Pre-building thickening of weak grounds of the port areas in the special conditions of drainage.

The object of the study is the deformation processes in the system "water-saturated ground base - vertical drains - loading mound", composed of soils that have the properties of filtration anisotropy and irreversibility of deformations during loading and unloading. The purpose of the work is to develop a methodology for calculating the sediment of the system "water saturated soil base - vertical drains - loading mound" in time, taking into account its spatial anisotropy of filtration properties and the irreversibility of deformations during loading and unloading of soil. Research methods - an integrated approach, including analysis and synthesis of information sources, statistical, research data, as well as scientific and technical achievements on the topic of the dissertation; Sediment bases, which are compacted using vertical drains; Theoretical studies using the provisions of soil mechanics; Theories of probability and mathematical statistics; Methods of mathematical modeling of geomechanical processes in soil basis. The scientific novelty and significance of the results of the work consists in establishing the regularities connecting the average sediments of the bases, which are compacted with the use of vertical drains and the loading from the side of the day surface, with anisotropy of the filtration properties of the soils and the irreversibility of their deformations during loading and unloading. For the first time, a solution is obtained for the distribution of displacements in a water-saturated base with an anisotropy of filtration properties, to the upper boundary of which a distributed load is applied. The results of the research have been successfully implemented in the calculation of the slump of the slab foundation of a residential house, in the development of a method for determining deformations in soil bases, and in the educational process.
