“…In these analyses, it would be important to compare the amounts and number of cyclical loads to the obtained results of the durability properties of the soil backfill. This gives a reason to continue these kinds of studies upon erecting such types of structures in order to expressly determine the relationships between service loads and the load-bearing capacity and durability of flexible steel structures (Asp and Laaksonen 2017). The author believes that such analyses would enable the determination of an additional coefficient determining the assessment of the load capacity during the operation time of these types of structures.…”

The article attempts to assess the changes in the properties of the soil backfill on the basis of studies carried out on the soil compaction indicator for a buried flexible steel structure located in a section of the Pan-European railway line. Initial tests on soil compaction showed that the backfilling does not meet the standard for railway structures. On this basis, it was decided to conduct additional studies taking into account the probability of compacting the soil during the operation of the structure. In order to verify any changes, the compaction indicator tests were repeated after 7 months of use under intensive railway load. On this basis, it can to be stated that there is relationship between the impact of a service load and the parameters of a soil backfill over time. As a result of the intense exploitation of a structure, an increase in the soil compaction index even up to 6.0% (average 2.5%) occurs.
