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.
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.
|INSTALLATION PERIOD||TYPE OF SENSORS||NUMBER OF SENSORS|
|1997||DiTeSt / DiTemp , SOFO||9|
