TECHNICAL CONDITION OF CORRUGATED METAL TRANSPORT STRUCTURES

Purpose. The purpose of the work is to establish real technical condition transport structures made corrugated metal on basis analysis scientific and sources.And analyze experience operation in soil environment form generalize problems ensuring reliability durability conditions railways highways Ukraine. Methodology. To achieve this goal, a review sources regulations different countries facilities Ukraine was conducted. In particular, data distribution bridges pipes by mode are given. It shown that development implementation new technologies for repair existing defective small bridges, both very important issue. A thorough Data main inadmissible defects reasons their CMS' (corrugated structures) corrosion other number examples overpass defects, collapse with MCS presented. qualitative indicators structures, advantages disadvantages also considered, CMS formulated. Findings. An domestic foreign world studied generalized. synthesis buildings Originality. As result operated Ukraine, it found about 15 % – medium culverts Ukrainian 45 roads have unacceptable require immediate replacement. Also, established research there no methods assessing load-bearing capacity presence body embankment railway or highway diameter greater than 6 m. determined standards don't include design monitoring tracks. Practical value. On these possible offer directions theoretical experimental calculation, tests diagnostics CMS. measurement impact bearing residual deformations pipe track. Execution calculation constructions will lead improvement
