Abstract
As part of Barcelona’s port expansion strategy, an extensive marine geotechnical investigation was conducted in a sheltered nearshore area of the southwestern area of the port. The primary objective was to comprehensively characterize the deltaic cohesive soft sediments in the Llobregat delta and provide a ground model for the design of new quays and container terminals as well as port facilities. The fieldwork was executed using a set of two jack-up platforms deployed at various locations, with water depths ranging between 8 and 20 m, achieving an average investigation depth of 40 m below the seafloor.
This paper presents select results from the investigation, focusing on a series of 8 triple points where three different site investigation methods were performed at the same location: Marchetti Dilatometer Tests (DMT), Cone Penetration Tests (CPTU), and rotary boreholes with SPT and thin wall undisturbed samples. A direct comparison of the results from different types of tests was performed in terms of soil classification, bulk density, and undrained shear strength. All data sets were analysed and the most suitable correlations for the site-specific conditions were defined.
