Influence of cyclic pile behaviour caused by surging and vibratory pile driving on the penetration resistance and bearing capacity
In a series of laboratory experiments, pile penetration resistance and the bearing capacity of a model pile installed by three methods (push-in, surging, and vibratory pile driving) in both dry and saturated sand ground were compared. It was observed that the pile penetration resistance decreased due to soil contraction caused by the cyclic pile behaviour of surging and vibration. Furthermore, the bearing capacity in the static load test (SLT) became higher than the pile penetration resistance at the end of the pile installation phase. This is because the contraction behaviour of soil became soil dilation under monotonic pile movement in the SLT. It was found that the pile penetration resistance and bearing capacity were related to the soil deformation behaviour, namely contraction under cyclic pile movement and dilation under monotonic pile movement.
