The Luzzone dam was recently raised by 18 m to increase the capacity of the reservoir.


 

Aim of monitoring:
 

The new concrete was instrumented with long-gage SOFO sensors to monitor its shrinkage deformations and to evaluate the interaction between the newly added concrete and the old one.

Main results:
 

The sensors survived unharmed the installation in the coarse concrete. Then sensors monitored the deformations over years of operation and showed results compatible with the finite-element simulations.
