Modified Calculation of Pile Group Settlement Interaction

摘要

A procedure is described for calculating group settlement interaction factors in which the influence of the greater soil mass stiffness between piles is allowed for. The procedure leads to decreased interaction between piles and to more uniform distributions of load than are obtained by the conventional analysis in which the soil mass modulus is assumed to be equal to the soil modulus near each pile. When applied to a recent series of field tests, the modified procedure is found to predict the group performance more closely than does the conventional procedure.
