Ambiesta Dam - Geophysical Survey to Define the Cracks Patterns inside the Structure

The paper describes the investigation using sonic tomography, performed on the Ambiesta dam (Italy) and aimed to characterize and identify the concrete cracking patterns inside the dam body, starting from the surevy of cracks visible on the downstream face.

The investigation had to define the depth of the cracks patterns and define the concrete caractheristics in the area affected by the cracks compared to healthy areas or free from cracks.
