To increase the capacity of the railway Divača – Prešnica – Koper, which in the future will no longer satisfy the needs of Luka Koper, the construction of the 2nd railway track Divača – Koper is planned. The project includes the construction of a service track, with a total length of 1.2 km. Part of the track runs on the embankment, which is the subject of this master's thesis.
Often happens that geotechnical conditions at the construction site are different from the projected ones. The main causes of “geological-geotechnical surprises” are the inadequate quantity and quality of geological geotechnical investigation and wrong interpretation of the results.
In the thesis reverse geological geotechnical analysis of the embankment and reinterpretation of measurements was performed. The obtained results were compared with the data provided by the geological- geotechnical design. Based on the comparison of the cone penetration test, flat dilatometer test and laboratory test results, we found out in which case the individual test gives inadequate result.
The settlements and consolidation time of the material model was compared with the data in the project documentation, to determine if the project was implemented safely, rationally and according to the prognosis. In order to analyze the embankment after the construction, we evaluate the settlements that were measured with horizontal inclinometers.
