Methods for Determining the Technical Condition of a Culvert With an Analysis of the Necessary Repair Work

Recently, there has been a deterioration in the condition of culverts, including those that were previously constructed, which is caused by the impact of the environment, physical wear and aging of materials and structures, increased axial loads, increased traffic flow, etc. The importance of transport structures, due to factors such as their strategic location, calls for the need to find modern construction solutions that combine fast execution, low cost, and satisfactory service life. Ongoing research and development in Europe include methods for determining the load-bearing capacity of existing bridges and structures; methodology for designing to assess fatigue resistance and ability to withstand cyclic loading; design methods for high-speed train load; life-cycle cost analysis, including consideration of environmental impact and the use of recycled materials. Future European research includes modern corrosion protection systems; higher-grade steel; deeper, larger corrugations; alternative metals and other materials; improved connection systems; improved backfilling; online monitoring systems for structures. Therefore, a current issue today is the use of modern approaches for carrying out repair measures with the application of effective repair materials to restore the operational properties of structures. It is recommended to provide design measures to ensure the geometric invariability of the pipe during the dismantling of the embankment and control the geometric parameters of the pipe elements during construction work, since the dismantling of the embankment can bring the existing system out of balance. An actual open scientific and technical issue remains the imperfect regulatory framework for assessing and predicting the technical condition of culverts on highways and railways. The work determins the technical condition of culverts and provides recommendations for its repair.
