Abstract

The effect of pre-loading a surface foundation is examined using finite element analysis. A given vertical load is applied to the foundation before the resulting undrained failure locus is calculated. It is seen that the application of vertical dead weight loading while allowing consolidation significantly increases the capacity of a foundation under combined vertical and horizontal undrained loading. The shape of the resulting failure loci are examined and it is noted that it is the horizontal capacity that is increased most significantly. Finally, simple design methods are presented to predict the increase in the size of the failure locus from pre-loading with differing vertical loads and consolidation times. Allowance of the resulting gradual strength gain of a foundation with time after installation may allow less conservative foundation design.
