GROUND SUBSIDENCE CAUSED BY EARTHQUAKE TYPE EXCITATION

Abstract

The extended CANAsand constitutive model, which incorporates the newly proposed  concept  of the  "Compact State", is used  in conjunction  with  the ID technique  to evaluate  the total subsidence  of a sandy deposit.   The  ID technique  is a simple  numerical procedure developed recently.  The results of the analysis clearly demonstrate  the importance of the initial void ratio of the deposit, its permeability and the depth of the overburden on the magnitude of the subsidence of the layer.
