Centrifuge Modeling of Coal Tailing Embankments
Centrifuge model studies were conducted on eight homogeneous dams with 1.75:1 slopes using coal tailings (waste coal, shale, fine sand, silt, and clay) to obtain experience on the behavior of this low-strength material in a laboratory setting and, further, to examine the accuracy of predictions of embankment failure by the simplified Bishop limit equilibrium method. The failure of four of the model embankments simulated typical features of slope failures observed in the field. Centrifuge modeling verified that the simplified Bishop method using standard measurements of soil strength properly indexed the dam safety but did not accurately locate the embankment failure surface. 20 refs.
