ABSTRACT
Modelling forces and displacements of stone columns, the width of shear zones has to be considered correctly. This applies for single columns and for groups of columns as well (Wehr 1999a, Wehr 2004). The influences of different parameters like initial density, pressure level and mean grain diameter on the width of the shear zone was studied intensively with model tests (Tejchman ’89, Hammad ’91, Hassan ’95) and could be reproduced with FE-calculations (Tejchman ’97, Tejchman et al. ’99).
