The cohesive frictional crack model applied to the analysis of the dam-foundation joint [PDF]
, 2010 The mechanical behaviour of dam-foundation joints plays a key role in concrete dam engineering since it is the weakest part of the structure and therefore the evolutionary crack process occurring along this joint determines the global load-bearing ...

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 ...
