Loading Rate Effects on Axial Pile Capacity in Clays
… axial load tests are performed on foundation piles. Traditionally, static tests with an average duration of approximately twenty-four hours have been performed on test piles to obtain their axial capacity. These static tests require multiple piles used as anchors in addition to the test pile. …

Uplift capacity of helical piles in thawing permafrost
… effect of subsurface 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 …

Sustainable slow maintained pile load test
… by contractors in Malaysia to ensure the driven pile could accommodate the design load of the structure. Slow maintained load test is a test to determine load-settlement curve and pile capacity for a period of time using conventional load test. Conventional static pile load test equipment is …

Improved methods for forward and inverse solution of the wave equation for piles
… for the static and dynamic analysis of driven piles for both forward and inverse solutions. Wave propagation in piles, which is the result of pile head (or toe) impact and the distributed mass and elasticity of the pile, was analyzed in two ways: forward (the hammer is modeled and the pile …

Characterization of "t-z" model design parameters for augered cast-in-place piles using field load test data
With the increasing use of augered cast-in-place piles in new construction, it is important that proper design parameters be incorporated when evaluating pile capacity and performance using reliability-based design methods. This paper focuses on developing “t-zâ€� model parameters from analysis …

Response of piled buildings to the construction of deep excavations
… mechanisms of soil-structure interaction for piled buildings adjacent to deep excavations to be used in the design and monitoring of deep excavations in urban areas. Most methods to assess building response have originally been developed for tunnelling projects or buildings with shallow …

A Laboratory and Field Study of Composite Piles for Bridge Substructures
Typically, foundation piles are made of materials such as steel, concrete, and timber. Problems associated with use of these traditional pile materials in harsh marine environments include steel corrosion, concrete deterioration, and marine borer attack on timber piles. It has been estimated that …

Guidelines for designing the overhead transmission tower foundations adjacent to cohesionless slopes
… effects of various parameters on their ultimate capacity. The research methodology consisted of three main components: i) conducting a series of laboratory tests on two types of overhead transmission tower foundations, namely: pad and inclined chimney footing and vertical and batter pier …

Scaling effect in cone penetration testing in sand
… a device which provides a small scale model of a pile foundation. Early versions were simple cone points for which the only measurement was the thrust required to push the point through the ground. Over the past 20 years, the cone was standardized to a tip area of 10 cm², and an electrical version …

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 …
