The potential of 3D numerical modelling for the interpretation of load tests on a sheet pile quay wall
The potential of 3D numerical modelling for the interpretation of load tests on a sheet pile quay wall
ABSTRACT: Load tests are essential to verify the actual behaviour of every large infrastructure and ensure the safety of the activities and workers. Paradoxically, there are situations in which the evaluation of the load test result is more challenging than the design of the work. This is the case of some strengthening and renovation of old geotechnical works in which an entirely new structure is added close to the old one, which is left in place. The design of the renovation can assume that the new structure is able to bear the entire working load on its own, so that the existence of the old structures is totally ignored. Differently, the evaluation of the load test result needs to consider the real arrangement of all the structures existing in the significative volume of soil involved in the test. In this paper, the availability of monitoring data relating to the activities carried out to renovate a large sheet pile quay wall in a major Italian port, allowed to explore the potential of 3D numerical analysis to assess the behaviour of the work taking into account the coexistence of old and new structures.
