PREDICTION OF LIQUEFACTION IN SAND DEPOSITS DURING EARTHQUAKES.

Abstract

A previously developed method for computing the progressive rise of pore pressures in saturated sands subjected to cyclic loading has been adjusted to fit data obtained from triaxial torsion tests. Also, the method has been incorporated into a computer code for the computation of pore pressures based on shear stresses obtained from an independent earthquake response analysis of the ground. The method has been applied in the three case studies involving sand deposits where actual acceleration records were obtained during recent major earthquakes. The predicted behavior of the sand deposits has been compared with the observed damage related to the deposits.
