MODEL PILE GROUP SUBJECTED TO CYCLIC LATERAL LOAD

[摘要] References(7)A 4-pile group of vertical, fiexible piles embedded in dense sand was subjected to cyclic lateral load, with and without vertical load acting on cap. Conditions of free rotation and no rotation of the cap were imposed. A single pile was also tested. Effect of cyclic load on horizontal deflection, rotation of cap and moments induced in the piles has been investigated. The deflection, rotation and moment were observed to increase at a decreasing rate with cyclic loading. Cap restraint reduced the corresponding changes. Effect of vertical load was not of significance.
