| Title of the article | Stability of the fastening elements of the slopes of transport structures under the hydrodynamic effects of sea waves |
| Abstract. | Problem statement. When designing transport structures located in the offshore coastal zone, the reliability of operation is ensured, among other things, by the effective operation of engineering protection structures against the effects of sea waves. In this work, the object of research is wave-damping slopes made of rough stone or shaped massifs located in the root parts of engineering protection structures (traverses, buns, etc.). The wave pattern of structures under the influence of waves approaching the slopes at angles in the 35–90-degree sector was studied. The work was performed using the method of physical (hydraulic) modeling. The purpose of the research is to adjust the methodology for calculating the stability of the fastening elements of slope wave damping structures, based on theoretical developments and experimental data (based on laboratory research data). The tasks are to perform physical modeling of wave effects on the fastening elements of wave-damping slopes at different angles of the approach of sea waves to structures; to propose formulas based on scientific research to supplement existing regulatory documents in the field of engineering protection of transport structures. Results. In this work, the conditions for the loss of stability of the fastening elements of the protective slopes are obtained, namely, the most unfavorable angles of wave approaches to structures. The obtained interference effects in the zone of wave effects on the fastening elements are substantiated. Calculation formulas are proposed for the most complete consideration of wave effects in the oblique approach of waves to structures. Conclusions. The conducted research aimed at developing and improving the regulatory framework in transport construction will improve the reliability and safety of roads and railways, as well as bridge crossings designed and operated on the sea coasts. It is recommended that the results obtained, based on scientific research, be reflected in the updated version of SP 277.13258.2016. |
