Modeling water penetration at dam-foundation joint [PDF]
, 2007 When fracture occurs in a concrete dam, the crack mouth is typically exposed to water. Very often this phenomenon occurs at the dam-foundation joint and is driven also by the fluid pressure inside the crack.

Advances on the Failure Analysis of the Dam—Foundation Interface of Concrete Dams [PDF]
Materials, 2015 Failure analysis of the dam-foundation interface in concrete dams is characterized by complexity, uncertainties on models and parameters, and a strong non-linear softening behavior. In practice, these uncertainties are dealt with a well-structured mixture of experience, best practices and prudent, conservative design approaches based on the safety ...
