Purpose: to study the performance of hydraulic structures of engineering protection of the Lower Kuban, based on the technical condition assessment using non-destructive gauges.
Materials and methods. The studies were carried out on various structures, taking into account the conditions for the formation of environment improving potential in the territory of southern Russia, using the example of Krasnodar Territory. Field studies and field tests were carried out according to the methods of Kuban State Agrarian University. The studies of the engineering protection system using a complex of non-destructive gauges which made it possible to get the most complete and accurate information about a spatial object, have been carried out, the physical-mechanical and filtration properties of soils were determined in individual reference sections by traditional methods.
Results. It has been determined that on engineering protection embankments, the filtration properties of composed ground depend on the degree of their compaction, the composition of bulk soils and the formation of drying cracks. The survey with non-destructive gauges was carried out using a georadar. The steel reinforcement by the hodographs of high-amplitude refracted waves was determined. The dimensions of the cracks by the violation of the amplitude reflection tracking were determined. When carrying out electrical exploration work on an earth low-pressure levee, the method of vertical electrical sounding was used. As a result of data processing and interpretation, the geoelectric sections of specific soil resistance were obtained.
Conclusions. The main reasons for the flood damage increase are socio-economic reasons, manifested in the active and at the same time irrational use of flood-prone areas. Results of the study confirm the effectiveness, productivity and information value of applicable geophysical methods at relatively low cost.
