The behavior of laterally loaded single piles and group piles in sand
… response of laterally loaded single and group piles in sand. A single surface, isotropic hardening constitutive model with nonassociative flow rule is used to model the behavior of sand. The purpose of the study is to gain a better understanding of the soil and pile behavior of laterally loaded …

Probabilistic analysis of laterally loaded piles
Includes bibliographical references (pages 66-74).

Behavior of Batter Piles in Sand
… 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 pile-to-pile cap connections for the prestressed concrete piles using full-scale static experimental results …

Theoretical study of the performance of piles.
… has been assumed that the soil surrounding the piles may be characterised by suitably chosen elastic constants. This assumption has enabled simple models of the behaviour of single piles under the action of vertical and horizontal loads, to be established; the models have led to more efficient …

Tunnelling Effects on Bored Piles in Clay
… the past, concentrated on tunnelling adjacent to piles and the effect on pile bending. Where work has been undertaken for tunnelling directly beneath piles, this has been directed at driven piles. As pile driving is less desirable in urban areas, owing to noise and vibrations, bored piling is …

Piles in Sand and in Sand Overlying Clay
… of single 60mm and 114mm segmented tubular steel piles driven and placed into loose sand and loose sand overlying clay. The soil was placed and instrumented under controlled conditions in a 3.0m diameter by 3.0m deep concrete tank. The 60mm pile was dynamically driven using a pneumatically …

Investigating the performance of continuous helical displacement piles
… auger, in a similar fashion to European screw piles and as such, it has performance characteristics of both displacement and non-displacement piles Based on field experience, it is known that the load capacity performance of the CHD pile significantly exceeds the current design predictions, …

Uplift capacity of helical piles in thawing permafrost
… temperatures on the axial capacity of helical piles embedded in silty permafrost soils. The overall of goals of this thesis are (1) characterization of the impact of different environmental and loading conditions on the axial capacity of helical piles and (2) development of meaningful …

Closed form solution of the wave equation for piles
… the one-dimensional wave equation as applied to piles used in the support of structures for civil works and driven using impact equipment. Since the 1950's, numerical methods, both finite difference and finite element, have been used extensively for the analysis of piles during driving and are …

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 …

Screw piles as offshore foundations : Numerical and physical modelling
… foundation solutions. In this thesis, screw piles (helical piles) have been proposed as a potential innovative alternative foundation for offshore wind turbines in deeper water. This type of pile has been used widely as foundation and anchor for onshore projects due to their ability to …

Analysis of consolidation around driven piles in overconsolidated clay
… for understanding and predicting the behavior of piles driven in highly overconsolidated clays (OCR24). The skin friction mobilized during pile loading to failure depends on the sequence of preceding events, i.e. pile installation and soil consolidation. This research utilizes the Strain Path …

Design verification of a diaphragm wall with steel piles
… verify the design of a diaphragm wall with steel piles. The original design was based on analysis performed on a soil-structure interaction program using soil parameters calibrated in a previous study. Original and "as-built" design models were compared to measured results of the constructed …

Influence of heave reducing piles on ground movements around excavations
The research concerns the influence of piles, installed beneath deep excavations, as a means of reducing movements in the surrounding ground. The work focussed on the use of piles installed as a part of top down basement construction, a technique used in conjunction with deep excavations in urban …
