For a bridge abutment to be supported on raking piles with different orientations, the movement between the ground and the pile group is difficult to predict.
For instance, if some of the raking piles of the bridge abutment are extended beneath an embankment, then the settlement of embankment behind the abutment may cause the raking piles to experience severe bending moment and damage the piles as recommended by Dr. Edmund C Hambly (1979).
