Paper presented at the ISRM International Symposium - EUROCK 2020, June 14–19, 2020
Paper Number: ISRM-EUROCK-2020-002
... Abstract Many of the concrete dams in the western world today have reached a considerable age. With an ageing population of dams, re-assessment of their structural safety is becoming increasingly important to ensure that failure does not occur because of material deterioration in the dam body...

The limit states slope stability using the reduced uniaxial compressive strength does not provide the same factor of safety when the reduced equivalent Mohr-Coulomb (MC) parameters are utilized in the analysis. This study aims at developing a...
