A 140m high arch dam in the Pyrenees, built in the 50s, is founded on fractured limestone rock. Since the beginning of the design process, two main families of discontinuities were identified, one being the bedding plane dipping 45 degrees upstream of the dam, and the second family being a set of vertical planes parallel to the river. The dam was built very close to the end of the narrow part of the valley, which raised stability concerns early on, leading to the construction of a massive reinfo...
