Abstract

Excavation of 75m of claystone at Asco Unit II resulted in foundation heave in excess of anticipated elastic rebound. The heave was found to be caused by expansive clay minerals in the rock swelling in the presence of water. Upper-bound estimates of future heave were made based on past trends, and structures analyzed to demonstrate their capacity to resist heave-caused deformations. The primary factor in controlling heave is the amount of water available to the bedrock.

Foundation Heave at ASCO II Nuclear Power Plant

Excavation of 75m of claystone at Asco Unit II resulted in foundation heave in excess of anticipated elastic rebound. The heave was found to be caused by expansive clay minerals in the rock swelling in the presence of water. Upper-bound estimates of future heave were made based on past trends, and structures analyzed to demonstrate their capacity to resist heave-caused deformations.
