EXPERIMENTAL STUDIES OF THE INFLUENCE OF WAVES ON THE BREAKWATER OF A PARTIAL VERTICAL PROFILE

Abstract

Abstract. The article is devoted to the issues of physical experimental researches connected with the determination of the parameters of wave quenching when overflowing them through the superstructure of enclosing hydraulic structures (ENS) of incomplete vertical profile. The research was conducted in the hydrowave laboratory of the Department of Hydraulic Engineering of the Odessa State Academy of Civil Engineering and Architecture. The article presents partial results of experiments performed on ENS of incomplete vertical profile. The models were made on a geometric scale and were subjected to wave effects similar to the conditions of the natural section of the coast of the Odessa Bay in compliance with the criteria of similarity. The construction of new structures of enclosing hydraulic structures requires careful primary experimental research. These researches mostly often carried out on physical models in specialized hydrowave laboratories, allow to get rid of risks of financial losses at the wrong choice of types and elements of the designed objects. The carried out researches allow estimating with a high degree of reliability, according to scale conditions, physics of the processes proceeding on models which will also be observed at the operation of real construction. The physics of the process of hydrodynamic impact on hydraulic structures is often difficult to describe only with the help of a mathematical model, which confirms the high degree of importance of physical experiments. The progress of technical science largely depends on the ability to make more accurate measurements. High-precision measuring equipment was used in laboratory tests. This paper describes the method of conducting experiments that were performed on one physical model, under three different conditions of the location of the superstructure relative to the quiet level, as well as different values of the initial wave heights. The use of structures of incomplete vertical profile, in order to protect the waters of seaports, as well as elements of the coastal infrastructure of maritime cities will increase economic attractiveness by reducing financial costs, thanks to the reduction of the topside of the enclosing structures.
