Abstract
The objects of the study are engineering structures for the protection of roads and railways, including bridge crossings located on the shores of the seas, from erosion caused by sea storm waves. Using the example of one of the most vulnerable sections of the Tuapse-Adler section of the North Caucasus Railway from the point of view of sea waves, traditional engineering protection structures were examined – an artificial wave-extinguishing strip with beach-retaining structures (sea booms) and a breakwater wall. The description of the operating conditions of hydraulic structures affecting their reliability is given. The characteristics of coastal protection options for the safety of railway operation are presented. When carrying out the research, materials from field surveys and field work carried out by the authors over a long period of time were used using mathematical and physical (hydraulic) modeling methods. Based on the results of the study, scenarios for the most likely and most severe accidents at offshore coastal protection structures protecting transport facilities have been developed. Consequently, in the scenario of the most severe accident at a hydraulic engineering facility, emergencies can reach a regional nature, and in the scenario of the most likely accident - a local nature. The proposed accident scenarios can be used to determine the value of the accident risk when assessing the likely damage that may be caused as a result of an accident of the considered engineering protection structures.
