ABSTRACT
The Line 6 of Naples Underground represents an important system of transport for the city of Naples., that will contribute to develop an integrated transport system implemented on highly interconnected and structured networks, in order to provide a balanced division of mobility between various transport means. The tunnel excavation was realized in urban environment, caracterized by very complex geological and geotechnical ground conditions. The ground deformations induced by the excavation tunnel, were controlled by an integrated monitoring system coupling conventional (optical leveling) and remote sensing technique between Mergellina and Chiaia of metro line during the work from March 2010 to December 2011. A good agreement with the measurements of displacements detected with the two different techniques can be observed; the satellite monitoring also allowed, in some sections, as to detect a continuous evolution of ground deformations even after the excavation phase.
