Behaviour of DCM columns under highway embankment at bridge approaches

The large post-construction differential settlement between a bridge and the backfill behind the abutment has been the major problem in the construction of expressway embankment over a soft clay foundation. There are many methods to treat the soft clay and to control the total and differential se...
