GROUND MOVEMENTS
The construction of the Koudiat Acerdoune dam, with a capacity of 450 million m3, has been entrusted by the National Agency for Dams to the company Razel.
Built in Roller Compacted Concrete, the structure is based on schisto-marl soil.
Work began in September 2002. However, significant ground movements (15 cm in total) and partial landslides are threatening both the work teams and the durability of the and the durability of the structure.
The challenge of monitoring and the isolation of the site led Razel to choose a solution that was both highly effective and robust solution.
A surveillance system was quickly installed by SIXENSE: 2 Cyclops and 125 targets are scanning the sensitive area 24 hours a day, in real time. The measured speeds are more than 1 cm/month, varying according to the weather and the works.
