Investigations of Pile Foundations in Brownfields
… to clean, improve and protect the environment. Piles foundations are often used in Brownfields to support structures. Regulators are concerned about the environmental safety of pile foundations in Brownfields sites. Piling in Brownfields may lead to transport of contaminants from the …

A Multicriteria Based Quantitative Framework for Assessing Sustainability of Pile Foundations
… multicriteria based sustainability indicator for pile foundations is developed that will aid the design and decision making processes of pile foundation projects. Specifically two types of pile foundations, namely, the driven concrete pile and the drilled shaft, are considered. The impacts these …

Seismic Response of Pile Foundations in Soft Clays and Layered Soils
Pile foundations are widely used to support large engineering structures by transferring loads to deeper layers of soil. During earthquakes, in addition to the axial loads, pile foundations are subjected to inertial loads and kinematic loads due to the motion of the superstructure and the …

An Experimental and Theoretical Study of Pile Foundations Embedded in Sand Soil
… the load carrying capacity of model instrumented piles embedded in sand soil, and to develop and verify reliable, highly efficient predictive models to fully correlate the non-linear relationship of pile load-settlement behaviour using a new, self-tuning artificial intelligence (AI) approach. In …

Implementation of an anisotropic plasticity model and its application to pile foundations problems
Pile foundations are used in more challenging site conditions, such as soft soils, to ensure both sufficient capacities and desired performance. As construction moves to more problematic locations and demands increase in magnitude and complexity, pile foundations have been required to accommodate …

Impact of Jet Grouting on the Lateral Strength of Soil Surrounding Driven Pile Foundations
… used to strengthen the soft soil surrounding the piles and the pile cap of two full-scale driven pile foundations. Soilcrete columns, created by jet grouting, were placed underneath the pile cap and surrounding the piles of the first foundation. Two rows of soilcrete columns were placed around the …

Behavior of Batter Piles in Sand
… of group interaction on behavior of small batter pile groups (3 x 3 and 4 x 4) were examined using the p-multiplier method proposed for the vertical piles. Average values of the p-multipliers appropriate for the small batter pile groups in sand were suggested. Investigations of various …

Ground penetrating radar characterization of wood piles and the water table in Back Bay, Boston
… depth to the water table and the tops of wood piles beneath a residential structure at 122 Beacon Street in Back Bay, Boston. The area of Boston known as the Back Bay was once a tidal estuary of the Charles River. During the latter half of the 19th century, the Back Bay was filled to create …

Reliability analyses for foundation and soil reinforcement applications
… analysis for selected topics including pile foundations, mechanically stabilized earth (MSE) walls and soil nail walls. The lognormal distribution is widely used to represent geotechnical parameters, such as pile resistance model bias, due to its non-negative property and mathematical …

Geotechnical centrifuge model testing for pile foundation re-use
… becoming more and more congested with redundant foundations. As the underground development of services and infrastructure already confines the location of building foundations, redundant foundations only add to this problem. The research described in this thesis, using centrifuge model testing, …

Enhancement of Shaft Capacity of Cast-in-Place Piles Using a Hook System
… the shaft bearing capacity of cast-in-place pile foundations by utilizing passive inclusions (Hooks) that will be mobilized if movement occurs in pile system. An extensive experimental program was developed to study the shaft bearing capacity of cast-in-place piles with and without hook …

Spiral Welded Pipe Piles For Structures In Southeastern Louisiana
… to. Historically, USACE has used concrete piles or steel H-piles as the foundations for these structures. Because of the magnitude of obtaining 100-year level hurricane protection, limited resources, and a condensed timeline, spiral welded pipe piles can be manufactured as an alternative to …

Experimentelle Untersuchungen zur Verformungsakkumulation und Tragfähigkeitsreduktion von zyklisch belasteten Pfählen
… with the effects of wind and waves, the foundations for offshore wind turbines are exposed to cyclic and dynamic loads. In this respect, different types of driven pile foundations, either the monopile or the multi-pile foundation, are frequently envisaged as foundation systems. Depending …

Deep Energy Foundations: Geotechnical Challenges and Design Considerations
… required for installation. Because Energy Piles perform the dual function of exchanging heat and providing structural support, and are only installed at sites where pile foundations are already required, these systems provide the thermal performance of deep geothermal systems without the …

FOOTING FIXITY OF BRIDGE PIER WITH END-BEARING PILE FOUNDATION
… the pier footing on multiple rows of end-bearing piles case. A comprehensive study using 20 models derived from the pier-pile design example presented by FHWA is developed for the finite element analysis using computer software. In order to investigate the difference of G values for different pile …

Assessment of Seismic Behaviour of Large LNG Tanks Considering Soil-Foundation- Structure Interaction
… of such heavy structures. Thus usually, deep foundations are used to support these tanks. Indeed, pile foundations are commonly used for these large tanks to transfer the load to competent ground layers and control the settlement. Generally, assessing the seismic resilience of these critical …

Dynamic soil modeling in site response and soil-large pile interaction analysis
… and 2) the effects of lateral spreading on large pile foundations. Two new soil damping formulations are implemented in non-linear one-dimensional site response analysis for small and large strains. The first formulation introduces an approach to construct a frequency-independent viscous damping …
