INFRASTRUCTURES
SUBSIDENCE IN CIVIL WORKS ANALYSIS
High-rise buildings, bridges, tunnels, dams, routes, among others, are construction works that are settled on the ground. Extraction of fluids or solids in sub ground layers produces settlements which eventually lead to changes in upper layers of the land cover where the aforementioned construction works are located. Therefore, even foreseeing all the construction factors, it is necessary to analyze sudden or high-value changes to safeguard infrastructure avoiding both human and economic losses.

The displacement measured by interferometric techniques achives centimetric and sub-centimetric precision over large remotely observed areas. Measurements that, in the case of the SAOCOM® satellites are possible at 8 days intervals. Therefore, by means of SAR measurements and the differential interferometry technique, it can be performed a continuous temporary analysis of ground movements and works that settle on it. Thus, it is possible to anticipate potential risks of damage to the structures.
