Multivariate analysis calculations of testing conditions of yield hinge at the top of the arch tubes showed that the origin of the yield hinge, which takes place in the vault of CIM is performed only on the condition of the simultaneous, the adverse effects of the two factors (reasons): the assumption of inequality way beyond the permissible values without performing measures to eliminate or limit its speed train (first cause); reducing soil compaction of backfill below 90% (the second reason). In the absence of a cause of the origin of the yield hinge will not happen. For the first time the carrying capacity of corrugated metal structures of large diameter (over 6 m) taking into account complex factors – the degree of compaction of backfill soil, the value of dynamic loading of rail transport by the criterion of yield hinge in the metal pipe in case of residual strains vertical and horizontal diameters CIM is investigated. The results of carrying capacity of corrugated metal structures such as horizontal ellipse cross sections can be used by engineers of bridge probationary stations of Railways and Ukravtodor and project organizations involved in the design of corrugated metal structures with a diameter bigger than 6 m.
