  • Modern methods for monitoring deformations of buildings and structures

    The object of the research, the result of which is the presented work, is a comprehensive system of spatial data of the railway infrastructure, within which a high-precision system of coordinates of the Russian Railways has been created, and methods definition of normal heights in the Baltic Heights System 1977. The strategy and prospects for the development of high-speed transport highways (VSM) have been described. Methods for determining normal heights at research sites are given.

    Keywords: monitoring, buildings, facilities, engineering and geodesic research, laser scanning, GNSS receivers, design, construction, observations, geodesic measurements

  • Main approaches to geomechanical monitoring of transport tunnels

    The article provides a brief overview of geomechanical methods for studying the stress-strain state of the soil mass and tunnel lining. The organization of monitoring in tunnels using conventional and fiber-optic systems is considered. Criteria for analysis of monitoring data and structural strength conditions are described

    Keywords: railway tunnel, construction, operation, monitoring, strain gauge, stress, strain, strength, bearing capacity

  • "Development of analytical methods of transformation and their application for space images processing "

    The research that results from the work presented is the means of transforming space imagery. A transformation method based on the use of projective geometry methods is proposed. A completed study of the proposed method for mathematical image and terrain models showed a high degree of accuracy and a number of advantages over traditional image transformations

    Keywords: Photogrammetry, transformations, cosmic images, projective geometry
