Abstract

This paper describes the application of a modified Newmarkian analysis method to the estimation of slope deformations during liquefaction-induced lateral spreading. The analysis method requires a pore-pressure history either predicted using a suitable constitutive model, or measured during a centrifuge or shaking-table test, to calculate the variation of threshold acceleration with time. Comparison of predicted displacements using this procedure and displacements measured in centrifuge mode1 tests with the same pore-pressure history shows good agreement.

Newmarkian Analysis of Liquefied Flow in Centrifuge Model Earthquakes
