Abstract

The results obtained from back analyses of two case histories of failures of small earth dams resulting from liquefaction of foundation soils are presented. The analyses have been performed in order to evaluate the deformation parameters used in a finite difference model (developed by Woodward-Clyde Associates), specifically those relevant to the liquefied soil layer. For both case histories, the final deformed shape of the earth dam is known and serves as a basis for comparing the results from the numerical study, in terms of the deformation moduli employed.

Backanalysis of Deformations for Case Histories Involving Flow-Type Failures

St. Louis, Missouri

The results obtained from back analyses of two case histories of failures of small earth dams resulting from liquefaction of foundation soils are presented. The analyses have been performed in order to evaluate the deformation parameters used in a finite difference model (developed by Woodward-Clyde Associates), specifically those relevant to the liquefied soil layer. For both case histories, the final deformed shape of the earth dam is known and serves as a basis for comparing the results from the numerical study, in terms of the deformation moduli employed.
