Abstract:
The Glen Elder Dam, completed in 1968, is located at the confluence of the North and South Forks of the Solomon River in north-central Kansas, near Glen Elder, KS. The Fort Randall Dam, completed in 1952, is located on the Missouri River in southeast South Dakota, near Pickstown. The spillway inlet apron slab at the Glen Elder Dam underwent significant renovation in early 2010. The spillway outlet apron slab at the Fort Randall Dam underwent significant renovation in 2013. This article highlights damage evaluation and repair of spillway slabs in both structures, including extensive use of hydrodemolition and a shrinkage reducing/compensating additive in the repair concrete.
