The Optimum Gravity Dam

Document Type: Proceeding Paper

Part of: Roller Compacted Concrete III


A method is presented for optimizing the cost of a dam by varying the properties of the material and the shape of the dam to produce the lowest cost water barrier to perform the required task. The idea is examined that a continuous spectrum of materials can be postulated between mass concrete on the one hand and rock fill on the other. Given the tremendous discrepancy in costs and properties of enriched earthfill materials and leaned-out mass concrete materials, it is shown that there is a great advantage in investigating the possibilities of the enriched soil materials. Diagrams are presented relating the costs of dams to the material properties and shapes of dams.
