Undrained Deformation Behavior of Partially Consolidated Boston Blue Clay
This report compares predicted and measured deformations of a soft clay foundation for a high embankment subjected to an increase in surcharge load. The 40-ft high embankment has been in place over 120 ft of Boston Blue Clay since 1968. During the summer of 1974, MIT and MDPW planned to load one station to complete failure to assess methods for predicting embankment stability. Detailed predictions of vertical and horizontal deformation for the additional loading were made by several methods, mostly before field loading began. These predictions are compared with the field measurements. Predictions of vertical undrained deformation by elastic theory, the method of D'Appolonia et al, which accounts for local yielding and a finite element analysis are within a 100% of the measured values with the finite element method overpredicting settlement and the other two methods underpredicting settlement.
