Basic Pile Group Behavior.

Abstract : This report is a revision of a Waterways Experiment Station Technical Report. It describes a computerized method for pile group design and analysis as practiced in 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 selection 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 analysis are also discussed. (Author)
