Possibilities of a dynamic survey method for hydraulic structures

Abstract

Establishing the category of a hydraulic structure’s technical condition is an urgent task that constantly requires solutions during operation. Both the operating costs and the safe operation will largely depend on the choice of a survey method and its reliability and validity. The method of structural dynamic diagnostics, which is becoming more widespread, is promising and relevant, however, based on the relative novelty of the method, its application requires closer attention, including consideration from the standpoint of numerical modeling.

Field studies to determine the deformations of low-pressure hydraulic structures

“…Deviations from the technology of construction work, as well as violations of the rules of operation of hydrotechnical constructions, can lead to their deposition and silencing. In the practice of construction of hydrotechnics, geodesic methods of determining deformations are adopted: geometric and geostatic leveling -determination of silgears by height; angle and target measurements for determining smooth in the plan [19,20]. Deformation of the structure by height is often manifested in the form of its deposition.…”

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

“…The standard list of works on the engineering survey of PHS includes instrumental and visual control of structural elements of structures in the surface and underwater zones. The technical condition of the structures is primarily determined on the basis of instrumental operations: geodesic survey with electronic high-precision instruments, determination of concrete strength by direct and indirect methods, visual surface and underwater (diving) inspection to identify defects and damages, depth measurements, etc [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. However, there are a number of difficulties, which does not allow to assess the technical condition qualitatively with the use of traditional survey methods.…”

Improvement of design parameters of geotextile containers made of polypropylene for removal of silt layers and industrial waste

“…For the manufacture of geotextile containers, the following types of polymers are most often used: thermoplastics; crystal thermoplastics; elastomers; thermoplastic elastomers [18,19]. Geotextile container made of high-strength fabric materials is a container made of filtering fabric geotextile in an unfilled state is presented in the form of a shell, equipped with a pump for water suspension supply (pulp from sediments, silt, sludge, soil) into the container (Figure 1).…”
