PHD THESIS
Background
Most of the small concrete dams in Norway
were built between the 1950s and 70s. The
safety of these dams are of high priority due to
severe consequences of failure. However, the
procedures of structural safety assessment was
developed 100 years ago and they need to be
updated. Furthermore, most dams which were
designed using existing guidelines at the time
of design need to be strengthened to meet the
increased safety requirements.
This project aims to understand the failure
mechanism in a concrete gravity dam and
mitigate the impact of increased safety
requirements for existing gravity dams.

Objectives of the study
•
Enhance fundamental knowledge of dams’
behavior
•
Propose new assessment steps for verifying
the stability of gravity dams
•
Identify and test methods and equipment
for destructive and (more importantly)
nondestructive testing (NDT) of materials
and assessing dams’ condition.
