The article deals with the problem of determining the stress state of a complex pile structure with end broadening in the form of a sphere in the soil mass in the analytical form by a discrete ...method. The calculation schemes for determining the stress tensor at the boundary of the pile of square and circular cross-section with expansions in the soil massif are shown. The elements of the polynomial are found by the discrete method in rectangular and spherical coordinates, which is a cumbersome complex mathematical apparatus for a modern design engineer. The stresses are determined. At present, as the analysis has shown, the solution of complex geotechnical problems of soil bases and foundations for different types of loads in numerical modeling is carried out using modern software. Numerical modeling and calculation with the help of specialized software systems allows to consider the system “building-foundation-ground foundation”, as dynamic, integrally developing. However, the interaction of the components of this system requires a theoretical justification of the resistance of foundations in the ground environment, especially in complex engineering-geological conditions.
The article presents a methodology for assessing the stability of construction objects to seismic impacts of the probabilistic approach, which can be used as the basis for the implementation of ...algorithms for automating the corresponding calculations during the design and operation of buildings and structures. The article also develops a technique for constructing finite elements, which makes it possible to consider the stress-strain state of deep-laid pile foundations for bridge supports on an elastic base with piecewise constant parameters. The developed technique based on the properties of Fourier images of finite functions, which allows calculating piles with end and surface widenings for dynamic effects.
Due to the unique water regime of the Astrakhan region, characterized by an uneven distribution of runoff that is directly dependent on the discharge from the Volgograd hydroelectric power station, ...coastal zones of water bodies are subject to intense negative effects. It is established that, despite the existing variety of ways to protect coasts from erosion, the search for new technical solutions at the moment continues to be an urgent task in hydraulic construction. The purpose of this work was to evaluate the application of a new methodology for studying the destruction of coastal zones and the method of shore protection. The article discusses the features of work on shore protection of territories subject to slope processes. The role of studies of the leading processes of destruction of coastal zones in the course of engineering and geological surveys, to predict and prevent risk, as well as to ensure the information content of further work on the construction of reliable shore protection, is emphasized. The result of the study was a new method for identifying the destroyed coastal zones, technologies for surface and deep fixing of the Bank slopes, and a method for preventing the collapse of steep river banks. In this paper, a positive assessment of the investigated method of Bank protection was given. Research has shown that prevention of emergency situations, especially in urbanized areas subject to intense anthropogenic impact, is possible only with the construction of engineering protection structures that have a positive effect in both protective and environmental aspects.
