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.

for Structural monItoringProject Coordinator: Prof.ssa C. Petrioli of the University of Rome ‘La Sapienza’

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.
