ANALYSIS OF PILE GROUPS SUBJECTED TO VERTICAL AND HORIZONTAL LOADS

Three methods of analyzing the behavior of pile groups are described, a well established statical method in which no account is taken of pile-soil interaction, a method in which the pile group is replaced by an equivalent structural bent and a method based on elastic theory in which interaction between the piles is taken into account in a logical manner. Comparisons between these three methods indicate that consideration of inter-pile interaction in the soil leads to increased maximum loads and moments in a group, although the deflections and rotations may not differ greatly. A parametric study is made of the deflections and rotation of typical pile groups, using the elastic interaction method. The effects of pile batter, increased pile spacing and increased pile stiffness in decreasing the group deflections and rotation are examined. /Author/
