RESEARCH OF THE REFLECTION COEFFICIENT OF WAVES FROM THROUGH-TYPE HYDRAULIC STRUCTURE WITH SUB-ВERTH SLOPE

Abstract

Тhe paper presents the results of experimental studies carried out on the basis of physical modeling using the latest measuring equipment and laboratory equipment from Wallingford (Great Britain). Loads from the force effect of wind waves are decisive when choosing the types and design features of offshore structures designed taking into account the natural and climatic conditions of each specific construction area. For this reason, the lack of accurate methods for calculating wave loads on offshore hydraulic structures does not allow ensuring their reliability during design and operation. The purpose of the presented experimental studies is to clarify and make additions to the section SP 38.13330.2018 [1] «Wave elements in a fenced water area», dedicated to determining the values ​​of the wave reflection coefficient for structures of through hydraulic structures, when exposed to the calculated wind waves. This topic in the regulatory document [1] is not considered broadly and extensively enough. But, at the same time, having information about the exact values ​​of the reflection coefficient of waves, it is possible to reasonably lower the elevation of hydraulic structures and carry out a number of constructive measures, which ultimately lead to a reduction in the cost of construction with a simultaneous increase in its quality.
