Abstract: The paper presents observations from a newly compiled database of static load tests comprising 68 instrumented drilled shafts and auger cast-in-place piles in sands, sand mixtures, silt mixtures, and clays at 37 sites ...

Abstract: This paper presents centrifuge data from model footing tests on dry sand, where a high resolution optical displacement measurement technique was employed to record subsurface soil displacements beneath the centerline of ...

Abstract: This paper presents a case history describing measurements made during the installation and load testing of groups of five, closely spaced, precast concrete piles in a soft clay-silt. The test results extend the presently ...

Abstract: This paper provides a rational method for evaluating a realistic lower bound for the base resistance of pipe piles in siliceous sand. Separate expressions are developed to represent the response to load of the pile plug, ...

Abstract: The paper presents the results from an experimental program carried out at Trinity College Dublin, in which instrumented model piles were jacked into loose dry sand in a large testing chamber. A number of pile installations ...

Abstract: This paper compares linear-elastic and nonlinear pile group analysis methods through settlement analyses of hypothetical scenarios and real case studies, and elaborates on the implications for interpretation of pile load ...

Abstract: The contribution to the uplift stiffness and capacity provided by the clay beneath the base of shallow footings typical in configuration to those employed to support high voltage electricity transmission towers is examined. ...

Abstract: This technical note presents results from a series of undrained load tests performed at model scale on circular embedded footings founded in a two-layered stratigraphy, comprising uniform stiff clay overlying soft clay. ...

Abstract: Comprehensive measurements of the effective stresses developed during the installation, equalization, and load testing of displacement piles in a loose to medium dense quartz sand are presented. The results shed new light ...
