| Title of the article | Assessment of the risk of accidents in engineering protection structures of transport facilities on the shores of the seas |
| Abstract. | Problem statement. Improving the reliability and safety of transport facilities located on the shores of the seas (highways, railways, bridges) largely depends on the effective operation of structures of engineering protection from the hydrodynamic effects of the natural aquatic environment. Reducing the risk of accidents on protective structures is an important task. Since the primary way to ensure the safety of structures in our country is to comply with the requirements of national standards of the Russian Federation and/or codes of practice, risk assessment should be carried out taking into account the availability, relevance and validity of calculation methods and applicable standards. The purpose of the research is to assess the risk of accidents on structures protecting transport structures from erosion by sea waves, in cases where the purpose of the loads is not sufficiently justified, or outdated calculation methods were used and, at the same time, the necessary regulatory and methodological documentation is partially missing. Research objectives: to perform an integrated hazard assessment, an integrated vulnerability assessment and an integrated risk assessment of accidents of hydrodynamic impacts of the natural aquatic environment engineering protection structures, depending on the availability, relevance and validity of calculation methods and applicable norms and standards. The work was performed by quantifying the risk of accidents (integral risk assessment) by obtaining normalization coefficients characterizing the proportion of the most unfavorable situation. Results. The work performs integral assessments of the danger and vulnerability of engineering protection structures of transport facilities from the hydrodynamic effects of the natural aquatic environment. Accident risk coefficients have been obtained for the most severe and least severe accident scenarios at such facilities. Conclusions. It is shown that the lack of relevant and reasonable calculation methods and applicable standards leads to a significant increase in the risk of accidents on structures of engineering protection of transport facilities from the hydrodynamic effects of the natural aquatic environment, and, consequently, significantly reduces the reliability and safety of transport facilities. |
