Development of p-y Curves of Laterally Loaded Piles in Cohesionless Soil [PDF]
The Scientific World Journal, 2014 The research on damages of structures that are supported by deep foundations has been quite intensive in the past decade. Kinematic interaction in soil-pile interaction is evaluated based on the p-y curve approach. Existing p-y curves have considered the

Applied Sciences, 2022 The removal of soil during scouring is crucial to the lateral resistance of piles in bridges of railways or highways. In this process, dilatancy of the interface soil induces variation in normal stress, which in turn influences the interface soil lateral

Nonlinear finite element Analysis of laterally loaded piles in Layered Soils
Electronic Journal of Structural Engineering, 2023 This work is based on Winkler’s theory to analyze laterally loaded single piles using the finite element method. Soil nonlinearity is taken into account via nonlinear springs “p-y” curves. Exact element displacement shape functions and stiffness matrix

Finite Element-Based p-y Curves in Sand
Arabian Journal for Science and Engineering, 2023 P-y curves are used in the prediction of non-linear soil resistance resulting from the horizontal pile movement. Many of the p-y curves have been developed in the 1970s for the petroleum industry to predict the horizontal capacity of piles supporting oil platforms.

Modified p-y Curves Method Based on Degradation Stiffness Model of Sand
Shanghai Jiaotong Daxue xuebao, 2020 Most of the existing p-y curves are based on the model test results of small-diameter pile under cyclic loading of finite times, which makes it difficult to accurately describe the displacement accumulation of large-diameter pile under long-term ...

Cyclic overlay model of p–y curves for laterally loaded monopiles in cohesionless soil [PDF]
Wind Energy Science, 2023 The bearing behaviour of large-diameter monopile foundations for offshore wind turbines under lateral cyclic loads in cohesionless soil is an issue of ongoing research. In practice, mostly the p–y approach is applied in the design of monopiles. Recently,

Evaluation of Curve Fitting Techniques in Deriving p–y Curves for Laterally Loaded Piles [PDF]
Geotechnical and Geological Engineering, 2016 The p–y method is one of the most popular methods for the analysis and design of laterally loaded piles. The mathematical relationship it provides between the bending moment, which can be easily measured at strain gauges along the pile, and the soil resistance and lateral pile displacement, facilitates the construction of p–y curves.

Investigation of p-y Behaviors of a Cyclic Laterally Loaded Pile in Saturated Silty Sand
Advances in Civil Engineering, 2022 This study aimed to evaluate the p-y behavior of pile foundations installed in saturated silty sand subject to cyclic lateral loading. Model piles were installed in saturated silty sand with three relative densities (40%, 70%, 90%), and lateral loads of ...

A Numerical Investigation to Determine the p–y Curves of Laterally Loaded Piles
Mathematics, 2021 This paper focuses on a numerical approach to finding the p–y curves for laterally loaded piles. The Drucker–Prager plastic model is employed and implemented within a finite element MATLAB code.

A practical method for construction of p-y curves for liquefiable soils [PDF]
Soil Dynamics and Earthquake Engineering, 2017 In practice, the analysis of laterally loaded piles is often carried out using a “Beam on Non-linear Winkler Foundation method” whereby the lateral pile-soil interaction is modelled as a set of non-linear springs (also known as p-y curves). During seismic liquefaction, the saturated sandy soil changes its state from a solid to a viscous fluid like ...
