ABSTRACT
ABSTRACT: The Urft dam, the Diemel dam and the Eder dam are three old masonry dams located in Germany. The paper describes the rehabilitation measures and the corresponding stability analyses carried out to adjust the dams to today’s standards. Remedial works such as the excavation of inspection galleries, the installation of a grout curtain with a downstream drainage screen as well as the installation of pre-stressed permanent tendons were carried out. In all three cases the stability of the upgraded dam could be proven on the basis of finite element analyses.
