Abstract
In this article, the object of research is the structures of engineering protection of bridge crossings from the hydrodynamic effects of the marine aquatic environment. The problems of design and evaluation of wave effects are considered in order to choose a method of engineering protection.
Mathematical modeling of wave conditions and lithodynamic processes in the coastal zone was performed using the example of a specific section of the Tuapse – Adler North Caucasian Railway. To protect against erosion by sea waves of five railway bridges located on this site, as well as the earthwork of the railway, three variants of engineering protection structures are considered: an artificial free beach (protective wave-extinguishing strip) with periodic operational replenishment, an artificial beach with beach-retaining structures (buns) and a wave- extinguishing berm made of stone.
The research was carried out by the method of mathematical modeling out according to the programs of Professor K. N. Makarov, implementing models of wave propagation and transformation, as well as lithodynamic processes of the coastal zone of the seas, which are the basis of the normative methods of SP 38.13330.2018 and SP 277.125800.2016.
Modeling of wave generation in deep water, their transformation and refraction in the coastal zone of the sea, as well as calculations of long-range sediment transport were performed using the developed digital terrain models.
Based on the results of mathematical modeling, the parameters of wind waves affecting structures in the offshore coastal zone of the site under consideration and the parameters of long-shore sediment transport were obtained. The volume of deposits to create a protective wave-damping band was determined, and the beach-holding capacity of the bun was evaluated. The parameters of the wave damping berm are determined.
