During the excavation phase the vibrating wire strain gauges and the load cells
are installed on the metal containment and support structures.

Geodetic measurements by total automatic stations
in Rome underground “B1 line”
Settlements and all kind of
displacements (inclination,
movements) are measured
by geodetic measurements
by total stations.
These measurements are
automatic and their
advantage is to cover a
great number of points in a
large area. Monitored area view

GENESI will develop a new generation of large-scale, heterogeneous, energy-efficient,
situation-aware wireless sensor networks for structural health monitoring and control
which are able to autonomously operate for several decades perfoming in situ
reasoning and evaluation of potential failures invisible to current monitoring.

Genesi sensor nodes are
applied to monitoring of Rome
underground “Linea B1” tunnel
under construction.
Each monitoring section is
constituted by 2 or 3 concrete
segments equipped with 6
strain gauges with vibrating
wire.
Optical prism location
For each monitoring section in a metro station the
following instruments are installed:
�inclinometer, having a length equal to the entire
vertical development of the diaphragm (1 piece)
�vibrating wire strain gauges, placed in pairs at
three different levels (6 pce) of the diaphragm
For each section of monitoring, a monitoring station
is located outside the station, consisting of:
�1 inclinometer
�1 borehole rod extensometer
�1 piezometer

Consorzio TreEsse is involved in Structural Health Monitoring activities during the
exacavation works of the new line of Rome underground “B1 line”. The total
length of the B1 line of Rome underground is 5 Km.
