The thesis deals with a geotechnical analysis of one of the settling pits that is used in the
Luka Koper seaport, for disposal of dredged material which has accumulated in the course of
waterway maintenance and deepening. The settling pit is located on the soft marshy ground
of Ankaranska Bonifika next to the Rižana River. It is surrounded by watertight embankments
on all sides. In the thesis, there are estimations of the ground properties based on
dilatometer and laboratory tests of the underlying soil and in close proximity to the pit. The
estimated properties are then used in calculations of the expected ground settlement and
overall stability of the structure. The computer program Rocscience Slide is used to calculate
the overall stability of the constructed pit. The first calculation evaluates an empty pit while in
the second calculation the pit is filled with the consolidated material.
The calculations for both stages of the pit reveal that the structure is not safe. An example of
an acceptably safe embankment with similar dimensions, built on the same ground is
provided.
All the calculations estimates in this work are done in accordance with the Eurocode
standards.
