Numerical parametric study on the influence of location and inclination of large-scale asperities on the shear strength of concrete-rock interfaces of small buttress dams

Bista, Dipen; Ulfberg, Adrian; Lia, Leif; Gonzalez-Libreros, Jaime; Johansson, Fredrik; Sas, Gabriel (Peer reviewed; Journal article, 2024)

When assessing the sliding stability of a concrete dam, the influence of large-scale asperities in the sliding plane is often ignored due to limitations of the analytical rigid body assessment methods provided by current ...
Probabilistic finite element analysis of failures in concrete dams with large asperities in the rock–concrete interface

Ulfberg, Adrian; Gonzalez-Libreros, Jaime; Das, Oisik; Bista, Dipen; Westberg Wilde, Marie; Johansson, Fredrik; Sas, Gabriel (Peer reviewed; Journal article, 2023)

Common analytical assessment methods for concrete dams are unlikely to predict material fracture in the dam body because of the assumption of rigid body behavior and uniform- or linear stress distribution along a predetermined ...
