Florida Department of Transportation (FDOT) sponsored research performed at the University of Florida resulted in developing a wireless monitoring and real time static capacity estimate technology for driven piles. This new technology, Embedded Data Collector (EDC), uses two levels of instrumentation, embedded in the body of precast prestressed concrete piles near the head and tip. Strain and a...

The stiffness and damping of pile foundations are proposed, which vary with the ratio of shear modulus Gi / Go to indicate the nonlinear properties of soil. The range of Gi / Go is defined with different vibration intensities for applications, and a computer program DYNAN is available based on the boundary zone model with non-reflective interface. Two engineering cases are studied to illustrate...

S: A series of centrifuge model tests were performed to assess the tunneling-induced ground deformations and their detrimental effects on the neighboring single pile in the saturated sandy ground. The relative elevations between the pile tip and the buried depth of new driven tunnel dominated the distributions of bending moment and axial force along the depths. A load transfer mechanism is prop...

The reliability index is an important reliability parameter that is necessary for the development of reliability-based geotechnical design. Both the factor of safety (FS) and the reliability index (β) represent safety margin of structures against either failure or limit state. In this study, the reliability index is analyzed and evaluated in reference to the factor of safety currently adopted i...

Pile heat exchangers – where heat transfer pipes are cast into the building piled foundations – offer an opportunity to use ground energy systems without the additional construction costs related to the provision of special purpose heat exchangers. However, analysis methods for pile heat exchangers are still under development. In particular there is an absence of available methods and guidance ...

The upper structure of high piled wharf in coastal soft soil area is loaded by waves or ships, which transferred to the foundation through pile foundation. force small and lasts for a long time, causes strength saturated clay vibration range decrease slowly, weakening effect gradually accumulates, resulting horizontal displacement In this paper, maximum residual are deduced calculated analytica...

The numerical prediction of vibration in buildings due to underground railways involves modelling many physical phenomena. Not least these is the dynamic soil-structure interaction that exists between various elements system. majority existing models assume railway tunnel and building’s foundation negligible, with two sub-systems behaving as though they are uncoupled. This paper presents some i...

This paper presents novel measurement data on the dynamic soil–structure interaction of an end-bearing pile foundation. The purpose is to assess ability predict foundation impedances based small-strain properties soil obtained from site investigations. Measurements were performed in two stages construction, allowing between piles through soil. First, single and factors experimentally for four w...

Suction caisson is a type of floor foundation for the offshore structures that is also called suction pile, bucket foundation, suction anchor, or sometimes ridge foundation depending on its application. In two past decades, this type of foundation has been widely used around the world as the fixed offshore foundation, anchor of the floating platforms, as well as the foundation of other marine s...
