Relevance of the research topic. In the practice of construction of civil and industrial buildings, various structures related to the elastic foundation are widely used. A large group of such structures consists of adjacent slabs and strips, which, according to the terminology of B. G. Korinev, are called non-insulated. Most non-insulated structures have floors in industrial and civil buildings, airfield and road surfaces, the bottoms of locks and dry docks, slabs of hydraulic structures, etc. is constantly in the focus of attention of many researchers.
The properties of the soils supporting these structures are very different. Usually, in the design samples of foundation soils, the physical properties of the soil are considered as a homogeneous isotropic body, the same at all points and in all directions. However, experimental studies show that almost all soils have anisotropic properties. This is due to the textural and structural features of the soil.
Thus, taking into account the anisotropic properties, the development of methods for calculating non-insulated structures on an elastic linearly deformable foundation is an urgent task. Obtaining specific analytical solutions to these problems will make design solutions economical and reliable.
The purpose of the dissertation workis to develop a practical method for calculating and analyzing the stress-strain state of 3 adjacent strips based on linear deformations of a general form, taking into account its anisotropy. In this case, you need to perform the following tasks:
- construction of the core of the foundation of an integrated model of a horizontal isotropic half-space;
- calculate the action of a force concentrated on 3 non-isolated strips lying on a linear deformable base of a general type by creating a mathematical model using computer programs, taking into account the properties of the soil;
- to determine the influence of the conditions of support of uninsulated strips, their dimensions, as well as the degree of anisotropy of the base on the stress-strain state of the plates;
- Quantitative analysis of forces and deformations of bandages under various external loads.
