Objectives

1) Evaluate the effect of pile spacing on measured p-multipliers and develop design curve for p-multipliers as a function of pile spacing. 2) Determine the validity of the p-multiplier concept for a larger (5 row) pile group and determine if p-multiplier values remain constant beyond the third row. 3) Determine the effect of cycle loading and gap formation in clays on the measured group effects and p-multipliers. 4) Examine the effect of cyclic loading and gap formation in clays on the measured dynamic resistance. 5) Evaluate the effect of pile diameter and stiffness on p-multiplier values for pile groups. 6) Evaluate the effect of uplift and compression on the lateral resistance of pile groups. 7) Provide a well documented case history for use in evaluating and calibrating computer and physical models.

Comments

Work has completed on this project. A draft final report has been sent to technical participants. A meeting will be held at Brigham Young University on March 29th to discuss the report findings. At this meeting, a proposal for a new pooled fund study for Phase 4 will be suggested. Phase 4 will look into passive resistance on pile caps. 2/14/01
