Survey methods for seaport waterworks on the example of the Balaklava Bay objects

Abstract

The article reflects materials on modern advanced methods of surveying the existing mooring and shore protection structures of the Balaklava Bay of the Republic of Crimea. The main purpose of the survey was to determine the technical condition and the actual bearing capacity of hydraulic structures, taking into account the existing physical wear. Article discusses the issues and problems of engineering survey and information modeling of marine port hydraulic structures using the example of existing objects. The application of such modern methods of inspection of hydraulic structures as sonar areal survey, ultrasonic thickness measurement, geo-radar study, seismic acoustic study of the depth of immersion of piles, underwater survey by means of remotely operated underwater vehicles is illustrated and analysed in present article. The experience of creating digital counterparts of port hydraulic structures using modern domestic software is considered. In the course of the work performed, it was confirmed that the exceptionally completeness and versatility of field research using modern equipment, as well as mathematical modeling in software and computing complexes, taking into account actual physical wear, can contribute to obtaining real reliable information about the available reserves of bearing capacity, durability and safety of the studied structures.
