Realistic failure modelling of concrete dams

Previous research projects have shown that finite element models are capable of capturing potential internal failure modes and can also consider potential combined failure modes traditionally not considered. The aim with this project is to assure a long-term, high dam safety level for concrete dams by developing knowledge and analysis methods based on realistic failure modes.

From a dam safety perspective, it is vital to maintain the long term safety of our dams despite aging infrastructure. Potential dam failures may result in a significant consequences with risk of loss of lives and great economical losses. Fortunately, relatively few dam failures have occurred historically. This does however also mean that there are limited data regarding dam failures and few documented cases where the failure progression was captured.

The aim with the project is to assure a long-term, high dam safety level for concrete dams by developing knowledge and analysis methods based on realistic failure modes. The outcome of the project will support activities like dam safety assessments, design of new dams and monitoring systems and for emergency preparedness purposes. A large amount of experimental data developed in a preceding SVC-project on the topic will be utilised to achieve this aim. In addition, new input regarding the impact from external boundary conditions, interaction between monoliths, and influence of existing cracks on the failure propagation will be used.
