Effect of Arrangement of Plugged and Unplugged Pipe Pile Group on the Contribution Ratios for Friction and End Resistance Capacity

  • EXPERIMENTAL INVESTIGATIONS

Soil Mechanics and Foundation Engineering Aims and scope

The tests were conducted in poorly graded sand prepared at three relative densities. Different parameters were considered such as method of installation, relative density, removal of soil plug, pile length to diameter ratio, and the ratios of friction and end resistance contribution with respect to ultimate bearing capacity. It was concluded that the contribution of the middle pile of the non-symmetric configuration group is 1.3 times the load carried by the edge pile, and this was observed for both the closed ended pile group and the open ended fully plugged pile group. Removal of soil plug from piles (single or group) causes a reduction in single and group capacities due to the elimination of two components, internal friction and confinement in the end bearing zone. The maximum reduction occurs in the dense state of soil with 61.5% and 83% for single and pile groups, respectively.
