Behaviour of laterally loaded piles in cohesive soils


The aim of this research is to develop a method to predict lateral pile displacement in clays and residual soils directly from in-situ tests such as the Cone Penetration Test (CPT). This project will include lateral pile load tests on site, centrifuge tests, and 3D finite element modelling.

Why my research is important

Foundations can be subject to lateral loads due to wind, wave, earthquakes, earth pressures and water pressures and piled foundations are commonly used to resist these lateral loads for onshore and offshore structures. It is currently common in the industry to estimate the behaviour of laterally loaded piles using the American Petroleum Institute (API) standards. The API standards recommends the use of non-linear load displacement (p-y) springs at various elevations in the soil stratum which provides an efficient method to predict pile displacement to failure. However, these p-y springs were developed based on research conducted on a limited range of pile dimensions and sizes, provides guidance on a limited range of material types, and is based on the laboratory strength of the material. Aware of the limitations to the API methods, designers often choose a conservative approach and hence resulting in a more expensive/ overdesigned option. This research project aims to mitigate these limitations and replace the current API methods for cohesive soils by developing a method to predict lateral pile displacement based on in-situ soil tests.
