Abstract:

Sixteen specially prepared laboratory soil specimens were subjected to model pile driving to induce grain crushing about the pile perimeter and study the effects grain crushing has on the engineering analysis of calcareous sediments. Each speciment constituted a particular material, level of degree of cementation, and density. The parameters measured for each test were the pile driving resistance, pile pullout resistance, and grain size analysis curves determined before and after pile driving for areas next to and remote to the pile surface. The results of this experiment revealed that crushability depends on the interrelated effects of grain harness, pile penetration resistance to driving, cement content, and soil density. A significant finding showed that the pile driving resistance is not a rational parameter in assessing pullout capacity for piles in calcareous sands. Author
