Deformation of crushed rock under plane strain conditions

The utilization of rockfill material for the construction of high dam, which in some cases reached 1000 ft (304.88 m) in height, has been greatly increased in recent years to meet the demand of storing large quantities of water and to generate more hydrauelectric power. Rock-fill materials are usually varies in size, shape, mineral composition, and capacity to allow the passage of water. Such variations are reflected on its engineering properties as strength and compressibility under load, which ultimately dictate the size and shape of the rock-fill core section of a dam.
