Experimental cyclic P-Y curves for saturated loose sand

, 2018
© 2018 ISRM International Symposium 2000, IS 2000. All rights reserved.A study on cyclic p-y curves that relate soil resistance to pile deflection in cohesionless soils near ground surface is the subject of this paper. Well-established p-y curve generation procedures are necessary for satisfactory estimation of the response of pile foundations in ...

Re-Examination Of P-Y Curve Formulations

Offshore Technology Conference, 1979
ABSTRACT In the analysis of piles supporting offshore structures, the key element in predicting the response to lateral loads is the determination of the appropriate lateral load - deformation relationships (p-y curves) for the soil.

Determination of Multidirectional p-y Curves for Soft Clays

Geotechnical Testing Journal, 2005
Abstract The evaluation of performance of soil-pile-structure systems under seismic loading is one of the most complex problems in earthquake engineering. In the most common methodology, force-displacement curves are used to describe the nonlinear response of discrete soil springs connecting the piles to the “free-field” soil column ...

Cyclic P-Y Curves for a Pile in Cohesive Soil

Geotechnical Earthquake Engineering and Soil Dynamics IV, 2008
A lateral load test was performed on a full-scale steel pipe pile installed in a soil profile consisting of cohesive, fine-grained soils with occasional sand layers. The pile was loaded in nine increments from 0 to 89 mm of displacement, with 15 loading cycles applied for each increment.

Cyclic p-y Curves in Clays for Offshore Structures

Offshore Technology Conference, 2019
Abstract Pile foundations supporting offshore structures are typically subjected to lateral cyclic loading. In design, the pile response under peak design load is generally estimated using a beam-column model where soil-structure interaction is simulated with a series of uncoupled non-linearly force-displacement springs (p-y curves ...

A method for p-y curve based on Vesic expansion theory

Soil Dynamics and Earthquake Engineering, 2020
Abstract In the recent years, the construction of urban infrastructure projects has developed rapidly. When the structure systems of these major infrastructures are subjected to various horizontal loads during operation, it may cause permanent lateral deformation of the pile and instability and damage of the foundation soil.

Experimental Evaluation of p-y Curves Considering Development of Liquefaction

Journal of Geotechnical and Geoenvironmental Engineering, 2013
AbstractAlthough evidence in the literature indicates that the lateral p-y resistance of piles in liquefiable soils is significantly reduced, the shape and amplitude of the reduced p-y curve during pore pressure buildup are needed for reliable design of pile foundations.

Development of p-y Curves for Partly Saturated Silts and Clays

New Technological and Design Developments in Deep Foundations, 2000
Lateral load tests were performed on 20 drilled shafts, 200 mm and 230 mm in diameter, at five sites in Virginia, where the foundation soils consisted of partially saturated silts and clays with both cohesion and friction. Laboratory strength tests were performed on undisturbed samples of the soils, and the deflection measured in the field tests were ...

P–Y Curves for Piles Under Seismic Lateral Loads

Geotechnical & Geological Engineering, 1998
This paper describes an experimentally based procedure for building dynamic P–Y curves for clays from the Campeche sound in the Gulf of Mexico and for Mexico City clays. Cyclic triaxial and resonant column tests were used to derive hyperbolic stiffness–strain and damping–strain functions that depend on soil plasticity and on relative consistency.

Uncertainty about p‐y Curves for Piles in Soft Clays

Journal of Geotechnical Engineering, 1986
Criteria for estimating the first two probabilistic moments of the normalized parameters of p-\Iy\N curves are presented. These parameters are the ultimate soil resistance and the initial tangent value of the soil reaction which are both normalized with respect to the values predicted by an adequate mathematical expression.
