Basic Pile Group Behavior.

Abstract : This report describes a computerized method for pile group design and analysis, as practiced by the Corps of Engineers, and proposes criteria for systematizing this method in a new computer program. Example problems are included. An overview of advanced methods of pile design and a brief discussion on selections of pile types, methods of installation, and allowable stresses are also presented. Estimation of soil moduli for laterally loaded piles and computation of pile stiffness coefficients for various soil conditions that are needed for the analysis are also discussed. (Author)
