Geotechnical analysis of a settling pit for the disposal of dredged material in Port of Koper

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