Multi-directional cyclic p–y curves for soft clays [PDF]

open access: yesOcean Engineering, 2016
Abstract Currently there is a lack of information and experimental data to formulate p–y curves in multi-directional loading conditions for soft clays. Experimental evidence has shown that uni-directional p–y curves are not able to represent correctly the near field soil response to multi-directional earthquake loading.

Genus one factors of curves defined by separated variable polynomials [PDF]

open access: yes, 2014
We give some sufficient conditions on complex polynomials P and Q to assure that the algebraic plane curve P(x)-Q(y)=0 has no irreducible component of genus 0 or 1.

P Y Curves of Laterally Loaded Piles Near Earth Slopes

open access: yesInternational Journal of Engineering and Advanced Technology, 2020
Design of piles under lateral loads using numerical analysis is a time-consuming process, requiring competent geotechnical engineers who can accurately model the soil profile and construction sequence. Therefore, most engineers have resorted to the p-y method that is a less time-consuming process in both the modeling and running time.

An explicit algebraic family of genus-one curves violating the Hasse principle [PDF]

open access: yes, 1999
We prove that for any t in Q, the curve 5 x^3 + 9 y^3 + 10 z^3 + 12((t^12-t^4-1)/(t^12-t^8-1))^3 (x+y+z)^3 = 0 in P^2 is a genus 1 curve violating the Hasse principle. An explicit Weierstrass model for its Jacobian E_t is given.

Bounding surface plastic p-y model for a single laterally loaded pile in sand

open access: yesYantu gongcheng xuebao, 2023
In ocean engineering practice, laterally loaded piles are usually analyzed using the nonlinear Winkler foundation beam method, in which the soil-structure interaction is modelled by means of the p-y curve, but now the API/DNV rules are only valid for few

Non-linear Analysis of Laterally Loaded Piles Using "p-y" Curves [PDF]

open access: yesGeotechnical 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.

"p-y" curves for piles in radially inhomogeneous soil [PDF]

open access: yes, 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 ...

Evaluating the Tutte Polynomial for Graphs of Bounded Tree-Width [PDF]

open access: yes, 1998
It is known that evaluating the Tutte polynomial, $T(G; x, y)$, of a graph, $G$, is $\#$P-hard at all but eight specific points and one specific curve of the $(x, y)$-plane.

Prediction of lateral capacity losses of a single pile adjacent to excavation of foundation pits based on CPT tests

open access: yesYantu gongcheng xuebao, 2019
The prediction of lateral capacity losses of a single pile adjacent to the excavation of foundation pits is made, by designing the excavation of a test pit in multi-layer soils based on CPT tests.

Modified p-y curves for monopile foundation with different length-to-diameter ratio

open access: yesBrodogradnja : 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.
