Abstract
The most common designs of breakwaters used for engineering protection of the roadbed are considered. Breakwaters are designed to dampen wave energy and retain sediments forming a wave-quenching beach. The purpose of the work is to develop criteria for the technical condition of breakwater elements by types of defects. The main research methods were a full-scale survey of structures and physical modeling in hydrowave pools and a tray. A survey of breakwaters on the section of the Tuapse – Adler railway line of the North Caucasus Railway (NCR) was carried out in order to determine defects in both structures as a whole and their elements. Experimental studies of the interaction of waves with breakwaters and the beach were carried out on models in wave pools and a tray. According to the research results, the division of breakwaters into separate elements according to their degree of weight is proposed. Criteria for the technical condition of each element of the breakwater by types of defects are obtained. An algorithm for assessing the technical condition of breakwaters and determining the necessary measures to ensure the operability of structures has been developed.
The proposed algorithm for assessing the technical condition of breakwaters will allow to assess their technical condition and thus improve the safety of the operation of the railway track on the pressure sea sections. The obtained criteria for assessing the technical condition of breakwaters are taken into account in the development of GOST R 59241-2020 “Coastal protection structures. Rules of inspection and monitoring of technical condition”.
