Rehabilitation of a Large Earth Fill Dam - Case History
Rehabilitation of a Large Earth Fill Dam - Case History
ABSTRACT: Mosul Dam is an earthfill dam built in the 80s on Tigris River, Iraq. Over the years, the structural integrity of the dam gave severe concerns, principally because of phenomena of dissolution of gypsum and anhydrite layers occurred in the foundation rock. In consideration of the critical situation characterizing the dam, in 2015 the Iraqi Government issued an international invitation to tender with an emergency procedure for the maintenance and safety of the dam. Trevi S.p.A. was awarded the tender: the contract included works for the repair of manufactured structures in correspondence of the bottom outlet and grout injections aimed at repairing the grout curtain. This paper focuses on drilling-and-grouting technologies and activities (carried out both from the embankment and the grouting gallery), successfully implemented for the refurbishment of the grout curtain.
