Effects of Cavities on the Mechanical Behavior of Pile Foundations in Weak Rock
In this study, a series of model tests was carried out on a small-scale single pile embedded in gypsum rock with predetermined cavities in order to investigate the effect of different cavity locations on the bearing capacity of the pile. This model was used to calculate a reduction factor for the bearing capacity of piles. Results show that the reduction factor decreased with an increase in the distance from the pile tip to the cavity. The reduction of the pile bearing capacity can be mainly explained by a reduction in the end bearing capacity of the pile. As can be seen from these results, pile capacity is significantly reduced when cavities are located close to the pile tip.
