The paper presents a case study on the response of an existing framed building founded on a deep basement to the construction of a 12 m diameter tunnel passing below it, in the city of Barcelona. Ground conditions on site involved a diverse range of soil materials, from very soft deposits to hard rock layers. The water table is located at a depth of about 10 m. The tunnel cover varies approximately from 30 to 36 m. Ground and building movements during tunnel construction were monitored. In the paper, the movements measured with conventional optical surveys are compared to those measured by multitemporal-InSAR analyses of satellite images. Hence, benefits and limitations of the latter technique in such complex Soil Structure Interaction (SSI) problem are discussed.

Abstract
The paper presents a case study on the response of an existing framed building founded on a deep basement to the construction of a 12 m diameter tunnel passing below it, in the city of Barcelona. Ground conditions on site involved a diverse range of soil materials, from very soft deposits to hard rock layers. The water table is located at a depth of about 10 m. The tunnel cover varies approximately from 30 to 36 m. Ground and building movements during tunnel construction were monitored. In the paper, the movements measured with conventional optical surveys are compared to those measured by multitemporal-InSAR analyses of satellite images. Hence, benefits and limitations of the latter technique in such complex Soil Structure Interaction (SSI) problem are discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
