One of the major difficulties in predicting the capacity of pipe piles
in sand has resulted from a lack of understanding of the physical
processes that control the behavior of piles during installation and
loading.
This monograph presents a detailed blue print for developing
experimental facilities necessary to identify these processes. These
facilities include a unique instrumented double-walled pipe-pile that is
used to delineate the frictional stresses acting against the external
and internal surfaces of the pile. The pile is fitted with miniature
pore-pressure transducers to monitor the generation of pore water
pressure during installation and loading. A fast automatic laboratory
pile hammer capable of representing the phenomena that occur during pile
driving was also developed and used.
