ABSTRACT
The failure mode of lime, lime/cement and cement columns will vary depending on the shear strength of the stabilised soil, the location of the slip surface through the columns, the failure strain and the lateral earth pressure on the columns. When the shear strength is high the columns could fail before the shear strength of the soil around the columns has been mobilised due to the small failure strain of the stabilised soil. A method is proposed where the reduction of the bearing capacity is taken into account as the columns are displaced laterally. This method to evaluate the bearing capacity has been compared with the stability of embankments on Orust and at Norrala.
