Work’s Geotechnical Consultancy
The Bemposta dam belongs to the Hydroelectric-power of International Douro. The new hydroelectric-power central of Bemposta II required a total investment of 130 million euros and increased by 80% the power of the existing central.
The alternative project for the excavation of the new water intake consisted of a sealig curtain to allow the construction of the cofferdam, definitive supporting structures for the slopes, with maximum height of 25m composed by reinforced concrete walls, with 0,5m thick and bolts along the entire height and anchored in the upper zone.
