Abstract : The report provides a means for predicting the ultimate settlements of cohesionless fallback materials and determines the nature of such settlements. A review was made of published data on laboratory investigations of crushed rock compressibility and field settlement data of rock-fill dams. The available data indicate that the fallback materials resulting from the formation of nuclear craters in rock will be subject to a continuing time-dependent settlement after deposition. The settlement should continue at a decreasing rate with time except that a marked increase in settlement can be expected when saturation occurs. (Author)
