ABSTRACT: In this paper, the case of a bulkhead in the Ravenna harbour is presented, where it was possible to monitor the behaviour of a steel sheet pile structure. This monitoring included inclinometer probes in the ground, topographical displacement readings at the top of the bulkhead, vibrating wire load cells on the anchors. On the basis of a good knowledge of the subsoil geotechnical characteristics, both in terms of the soil stratigraphy and of the constitutive behaviours of the various soils, a finite element numerical model of the problem, both in 2D and 3D, was used to analyze the data from the monitoring and to interpret the observed displacement fields. From this work some conclusions about the selection of the appropriate numerical scheme and of the soil constitutive modelling to better represent the observed behaviour were reached; such conclusions appear useful in the design of these very common marine infrastructures.
