Centrifugal Modeling of Axially Loaded Piles.

Abstract

The determination of a pile's capacity involves a variety of analytical and empirical procedures, static load tests, and dynamic measurements, none of which is satisfactory in itself. Research into behavior of piles has heretofore been hampered by the excessive costs of driving and testing piles strictly for research purposes, and by the variability of soil conditions within a test site. This thesis presents the results of research in the behavior of axially loaded piles using centrifugal models. Scale models offer the obvious advantages of reduced cost, ease of handling, and controlled test conditions. A centrifuge is used to provide the gravity field necessary to properly represent body forces due to self-weight of the soil. This investigation involved a series of tests on a prismatic pile and three tapered piles in a dry granular soil. The purpose of the research was to develop a system whereby piles could be driven and load tested while being rotated in a centrifuge, and, subsequently, to determine effects of taper on pile behavior.
