Abstract:

  This report presents the results of the numerical simulations performed at Princeton University within the framework of the "Class A" prediction phase of the VELACS project.

Predictions for all the proposed centrifuge model tests have been performed, using the multi-yield plasticity constitutive model implemented in the finite element code DYNAFLOW. The constitutive soil parameters are evaluated based on the results of conventional laboratory soil tests performed by the Earth Technology Corporation, and by empirical correlation formulae available in the literature. The parameter identification procedure is explained in details, and a unique set of constitutive parameters is used throughout the numerical simulations.

The present report contains all the numerical simulation results, comments and conclusions, as first submitted in the September 15, 1992 "Class A" predictions report. The numerical predictions - excess pore pressures, accelerations and displacements - are plotted for all the transducer locations. In order to meet the page restrictions imposed by the publisher, the dimensions of some of the figures are modified.
