This article presents the results of experimental studies of the stability of wave-damping slopes to protect bridge supports from wave action. The object of the study is the construction of protective wave-damping slopes constructed to protect the supports of bridges designed and operated under wave action conditions (such as the bridge to Russian Island in Vladivostok, etc.) on the shores of the seas. The purpose of the work is to select the optimal design solutions for protective slopes that ensure reliable and safe operation of the bridge crossing during sea storms of rare frequency. The research was carried out by the method of physical modeling in a wave pool. Various variants of structural solutions of protective slopes are considered: from a stone outline and from gabions, as well as combined structures. According to the results of research on a physical model in the wave basin, the structures of the protective slopes of bridge supports that are most resistant to the effects of sea storm waves of rare frequency have been obtained. The results of the research are intended to select optimal design solutions for protecting bridge supports from wave action and can also be used to protect other transport structures, for example, the roadbed of railways designed on sea coasts. These results were used by the author in the development of the regulatory framework for the design and monitoring of engineering structures for the protection of transport structures from wave action.

“…Strong winds can impose noticeable pressure imbalance and surface shear stress forces at the water surface, which can significantly influence wave-shoaling energy [5], as well as the wave-breaking process [6]. Driven by strong winds, ocean surface waves tend to break in advance in a deeper-water region [7]. Meanwhile, wave overtopping of coastal infrastructures and wave runup processes can be greatly affected by strong wind, as reported in the experimental works of Ward et al [8][9][10].…”

Driven by strong winds, huge ocean waves can cause devastating destruction to coastal regions during harsh weather events. There is growing evidence showing that extreme waves can occur in both shallow and deep waters. To protect the coast against the destructive power of huge waves, coastal protection facilities, such as seawalls, are often built along the coast. The integrity and stability of these coastal protection facilities are essential to the safety of coastal regions. Since huge waves are often accompanied by strong winds in real ocean environments, to fill the knowledge gap left by previous relevant studies, this study numerically investigates the hydrodynamic loads and overtopping of a coastal seawall model on a sloped beach under the coupled impact of an extreme wave group and wind. The influences of several main factors are considered, such as water depth, wind speed, and significant wave height. The research results reveal that strong wind can greatly increase the average overtopping rate and enhance the hydrodynamic loads exerted by the extreme wave group on the seawall.

Spur dikes are one of the types of structures for engineering protection of the roadbed, which, in combination with a wavedamping beach, are used to protect the railway track from wave action.The objective of this work is to improve safety of coast railway track operation in areas subject to wave action. The author used the methods of experimental research and survey for obtaining the criteria for assessing the technical condition of spur dikes.Based on the results of the survey of spur dikes, conclusions were drawn about low quality of construction, and the main types of defects were identified both in entire structures and in their elements. Experimental studies on hydrowave models were carried out to assess the beachholding capacity of the spur dikes and their resistance to wave action in the wave basin. It was proposed to divide the spur dikes into separate elements according to the degree of their significance, and the criteria for the technical condition by types of defects for each element of the structure under consideration were obtained.The technical condition criteria obtained from the results of surveys and experimental studies make it possible to assess the technical condition of spur dikes, which will increase railway operation safety.
