Determination of P-Y Curves Using Inclinometer Data

Geotechnical Testing Journal, 1994
Abstract Derivation of p-y curves from lateral load tests on deep foundations is a tedious and expensive task, requiring large numbers of strain gages along the length of the pile to develop bending moment versus depth relationships. A method is proposed which allows derivation of p-y curves from simple inclinometer data using a least ...

Theoretical p-y Curves for Laterally Loaded Single Piles in Undrained Clay Using Bezier Curves

Journal of Geotechnical and Geoenvironmental Engineering, 2010
An alternative method was introduced for predicting the nonlinear p-y curves for monotonic unidirectional laterally loaded single piles in uniform undrained clay. On the basis of numerical studies, closed-form solutions were developed for locating the start of yield (y e ); the ultimate yield point (y u ); and the initial stiffness, K i of the p-y ...

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.

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.

Lateral Force–Displacement of Piles—p-y Curve

2017
Many types of loading such as those induced from earthquakes, wind, ocean waves, traffic (bridges), thermal movement, water pressures (dams), and blast loads can generate lateral forces on vertical piles with a direction perpendicular to the axial direction of piles.

p-y Curves for Rock and Intermediate Geomaterials Using Pressuremeter Tests

Art of Foundation Engineering Practice, 2010
This paper presents proposed modifications to the existing methods that were originally developed to derive in-situ p-y curves from pressuremeter tests in soils to apply for pressuremeter tests in rock and/or intermediate geomaterials. The derived in-situ p-y curves can be used for the design of laterally loaded drilled shafts in rock and/or ...

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 ...

Structural Analysis of Frame-Type Levee Using P-Y Curve Method

Applied Mechanics and Materials, 2013
Frame-type levee is common type of levee in southern China. The deformation of pile foundation of frame-type levee is affected greatly by the river level. Large deformation is its notable feature. Taking levee project located in Wuzhou city of Guangxi province of China as research background, “P-Y curve” method is used to analyze the deformation and ...

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 ...
