GEODESY AND LAND MANAGEMENT IN SOLVING PROBLEMS OF STABILITY AND SAFETY OF HYDROTECHNICAL STRUCTURES, ANALYSIS OF MONITORING AND DIAGNOSTIC METHODS

The purpose of the article is the development and research of stability and safety of hydrotechnical structures using geodetic methods. The tasks set in the work are solved by analyzing the database of satellite geodetic and surveying systems. Method. The use of satellite technologies that allow determining the spatial position of hydrotechnical structures in automatic mode to solve the problems of increasing safety and stability. Analysis of monitoring and diagnostics in accordance with the strategic direction of scientific and technical development. The results. The main principles, advantages and limitations of the technology of satellite geodetic monitoring of deformations of hydrotechnical structures are described. Recommendations are given regarding the optimal composition, configuration and functional structure of satellite monitoring systems. It is noted that the use of satellite technology in combination with traditional monitoring methods increases the reliability of landslide detection and, as a result, the safety of the hydrotechnical structure and the population of the surrounding areas. Scientific novelty. The joint use of satellite and inertial measurements for surveying is substantiated, and a theoretical data processing solution is implemented. Problems of stability and safety of hydrotechnical structures have been solved. Practical significance. The obtained results can be used in geodesy and land management to develop comprehensive plans for the stability and safety of hydraulic structures.
