This paper presents some of the data obtained from the monitoring of two deep excavations carried out for the construction of two underground stations for the subway line B1 in Rome. Specifically, the focus is on the displacements of the retaining structures and of the ground surface. The measured displacements are related with the various construction stages, enabling a comprehensive assessment of the behavior of the structures in relation to the different techniques used for excavation support.

摘要

This paper presents some of the data obtained from the monitoring of two deep excavations carried out for the construction of two underground stations for the subway line B1 in Rome. Specifically, the focus is on the displacements of the retaining structures and of the ground surface. The measured displacements are related with the various construction stages, enabling a comprehensive assessment of the behavior of the structures in relation to the different techniques used for excavation support.
