Abstract
Purpose. The purpose of this paper is to conduct a study of the stress-strain state corrugated metal structures in the interaction with the soil backfill. Such studies will help to establish the causes of defects corrugated metal structures, which help to provide timely engineering solutions, which in turn can lead to increased carrying capacity ofthe CIM. Methodоlogy. Calculations of the stress-strain state corrugated metal structures made by finite element method using the licensed program FEMAP with MSC NASTRAN. In carrying out these calculations take into account the degree of compaction of backfill soil and the magnitude of the dynamic load of rail transport. Findings. According to the calculations, the margin structures ranging from 45% to 34%, depending on the degree of compaction of backfill soil, and for the emergence of early irreversible plastic deformation, an external load to be exceeded more than 2.48 times compared to the load at the design state track and loads on the track, which has allowed inequality.Originality. First Settlements stress-strain state corrugated metal structures under interaction backfill with soil, taking into account the complex factors such as the degree of compaction of backfill soil and the magnitude of the dynamic load of rail transport. Practical value. The results of the stress-strain state corrugated metal structures can be used to beat designers and engineers of test bridges stations Railways and Ukravtodor.
