Pile Load and Lateral Stability of Piles in Pile Group

摘要

The methods available for designing pile group foundations are handicapped by the lack of theory to relate the behavior of pile group foundations to that of an isolated single piles and also by lack of understanding of soil-pile behavior. Although a number of model and full-scale tests have been performed and analytical studies have been made in terms of soil-pile behaviors and pile group behaviors, there has been a need for a comparison and appraisal of the studies made to date in terms of lateral and vertical stability of pile group foundations. This report is the result of the review and evaluation of past and current research on lateral and vertical stability of pile group systems and soil-pile behavior. The study has been conducted by means of a literature search and direct inquiry to all state highway departments and others. The results of the study are useful in providing information essential to design of pile groups and to the conduct of additional research. (Author)
