Mitigation of ground and retaining structure displacements due to excavations: analysis and modelling of soil structure interaction
The research is developed in the field of soil-structure interaction studies, focusing particularly on the retaining structures for deep excavations and on harbour berthing structures. As regard the first topic, the constant increase in the population of large cities leads to an ever-growing demand for infrastructures, which is often only possible through underground constructions. The execution of an excavation inevitably involves a change in the stress state of the ground and consequently it induces displacements and deformations. In urban environment and, particularly, in presence of a cultural and artistic urban heritage such as that of Italy, it is of crucial importance to minimize such induced displacements. This problem has led over the years, on the one hand, to the development of calculation procedures capable of providing reliable predictions of the effects induced by the execution of deep excavations and, on the other, has encouraged the investigation of construction solutions capable of reducing such displacements. The objective of the study, developed through numerical analyses, was to deepen the knowledge on the deformation response of different types of retaining structures, with the aim of providing design guidance in terms of the reliability and applicability of some “unconventional” retaining structures (buttress walls), also to meet current demands in the engineering field. From the results produced by the accurate 3D numerical analyses, indications of the magnitude of the displacements and the extent of the displacement zone in the vicinity of the excavation, associated with different geometric configurations of the retaining structure, were obtained, with the aim of providing practical feedback for design purposes, for the validation of results obtained by less thorough and accurate studies, under similar conditions, In addition , the results of the 3D numerical analyses, provide useful insights and indications within a preliminary design phase. A second topic taken into consideration in the ...
