Shallow-layer p-y curves for single micropile in sands
Yantu gongcheng xuebao, 2018 Micropiles are increasingly used in seismic design or retrofitting for pile foundations. This study aims to investigate the validity of the widely used p-y relationships proposed by the American Petroleum Institute (API) and the ‘m method'; in the ...

Effect of Slope on P-Y Curves Due to Surcharge Load
Soils and Foundations, 2008 An extensive program of laboratory model tests was undertaken to study the effect of slope on p-y curves due to surcharge load in dry sand. The paper concerns the method developed in a series of laboratory model tests to experimentally determine p-y curves.

Preprint: Murmurations of Elliptic Curves
, 2022 We investigate the average value of the pth Dirichlet coefficients of elliptic curves for a prime p in a fixed conductor range with given rank. Plotting this average yields a striking oscillating pattern, the details of which vary with the rank. Based on

"p-y" curves for piles in radially inhomogeneous soil [PDF]
, 2023 “p-y” curves are used to simplify the pile response of laterally loaded piles at any given depth by describing the applied lateral soil reaction as a function of the lateral displacement. Simple analytical solutions in two-dimensions for system stiffness are available by modelling a segment of the pile surrounded by an annular zone of linear-elastic ...

Non-linear Analysis of Laterally Loaded Piles Using "p-y" Curves [PDF]
Geotechnical and Geological Engineering, 2020 In this paper, we analyze the behavior of a monopile under lateral loading. Specifically, this work focuses on the examination of the static stiffness coefficients of a monopile vertically embedded in a homogeneous or multilayer soil of random geometry and random mechanical properties.

Fourier restriction to polynomial curves I: a geometric inequality [PDF]
, 2010 We prove a Fourier restriction result for general polynomial curves in Rd. Measuring the Fourier restriction with respect to the affine arclength measure of the curve, we obtain a universal estimate for the class of all polynomial curves of bounded ...

P-y curves on model piles: Uncertainty identification
, 2010 The aim of determining the P-y reaction curves. The instrumented pile allows the bending moment profiles to be obtained. The uncertainty on the moment measurement is first quantified. The displacements are determined from a polynomial function fitted on the moment data and calculated by double-integrating the moment.

p-y curves for lateral bearing behavior of strength composite piles in soft clay
Yantu gongcheng xuebao, 2020 The strength composite (SC) pile is a novel type of pile technology which combines high-strength concrete piles and deep cement-mxing (DCM) columns. To attain a theoretical approach for the lateral bearing capacity of SC piles in soft clay, the cement ...

Modified p-y curves for monopile foundation with different length-to-diameter ratio
Brodogradnja : An International Journal of Naval Architecture and Ocean Engineering for Research and Development, 2023 The soil reaction of the monopile foundation subjected to lateral loading in offshore wind turbines is typically assessed relying on p-y curves advocated by API. However, this method is inadequate for gradually increasing monopile diameters and significantly underestimates the lateral soil confinement.
