The Use of Geodetic Methods in the Technical Examination of Hydraulic Structures from Soil Materials

Abstract

In our country, particular attention is paid to the safety of operating hydraulic structures, operational reliability of which is an integral part of the overall security of the Russian Federation. The security and energetic efficiency of hydraulic structures is regulated by the Town Planning Code of the Russian Federation, federal laws, and the code of rules “Hydrotechnical Structures. Key Points” [1-4]. Recommendation on the implementation of federal state construction supervision by officials of Rostekhnadzor (Federal Environmental, Industrial and Nuclear Supervision Service of Russia) during the construction and reconstruction of hydraulic structures are contained in methodological recommendations [5, 6]. Investigation of the operational reliability of soil hydraulic structures issue and the development of measures to extend the established term of their operation is a pressing challenge. To solve this challenge, the technical examination of hydraulic structures from soil materials, which allows us to assess the state of strength properties and the stress-strain state of dams, dikes, etc. is of great importance.The vast majority of soil dams are checked only visually, which does not allow to reliably assess their strength properties. To determine the development of infractions in the body of the dam, to determine the amount of washed soil at hydraulic structures, etc. geodetic methods of research can be used, which, compared to the visual methods, are more accurate.In order to determine the capabilities of geodetic methods for determining the volume of washed soils at hydraulic structures, the authors carried out experimental work to determine the volume of washed soils of the coast protection structure “Gluhaya Damba” (“Deaf Dam”) in the ash-disposal area near Zaimskiy island in the Omsk region.
