Settlement of Thick Clay Deposits under Piled-Raft Foundation and Design Considerations (Pile Dimensions)
Abstract: Characteristics and
histories of the deltaic deposits in geotechnical perspective are studied.
Geotechnical issues of clay deposits under floating foundation systems also
analyzed. Theoretical expressions and parameters were examined by an
experimental study and numerical analysis on the laboratory scales and field
measurement in this study. Also, piled raft foundation on thick clay deposits
is designated to optimize pile configuration. The predictions of settlements of
piled rafts foundation are proposed based on pile dimensions by utilizing a
normalized Ap/nL and Bg/Br. Practical design of piled raft foundations is made
for the light bridges and five story buildings on thick clay deposits to
discuss the long-term settlement, and it is found that the piled raft is well
applicable and effective on thick clay deposits, and that differential
settlements of the foundation should be managed by designing the configuration
of pile lengths and spacing.
