Abstract
Stompdrift Dam is a multi-arch structure located near De Rust in the Western Cape in South Africa. The dam comprises three double curvature arches which are separated by two buttresses. The left abutment is in rock whilst the right abutment is in the form of a gravity wall formed on a horizontal rock foundation. Between the right arch and the gravity wall there is a transition provided by a flank buttress. The gravity wall is ignored in this analysis as the resistance to the right arch thrusts is provided by the buttress. Furthermore, the stresses in the gravity wall can be found by classical analyses.

Stompdrift Dam is situated on the Olifants River. The height of the dam above the lowest foundation level is 49m and the total crest length is 364m. The dam was constructed mainly for irrigation purposes and was completed in 1965.
