This report presents the results of the Treasure Island Liquefaction Test (TILT), a joint project carried out by the University of California, San Diego, and Brigham Young University. To improve our understanding of the lateral load behavior of deep foundations in liquefied soil, a series of full-scale lateral load tests were performed at the National Geotechnical Experimentation Site (NGES) at Treasure Island in San Francisco, California. The ultimate goal of the TILT project was to develop lateral load-displacement relationships for a variety of individual piles and pile groups in liquefied sand under full-scale conditions. The tests were carried out using a high-speed hydraulic loading system after the sand surrounding the piles was liquefied using blasting techniques. This report presents backcalculated p-y curves for single pipe piles, pile groups, and cast-in-steel shell piles before and during liquefaction, as well as through dissipation of excess pore water pressures. In addition, recommendations with regard to design of deep foundations in liquefied soil are presented.

This volume on “Advances in Analysis and Design of Deep Foundations” contains 22 technical papers which cover various aspects of analysis and design of deep foundations based on full-scale field testing, numerical modeling, and analytical solutions. The technical papers are 8-10 pages long that present the results and findings from research as well as practical-oriented studies on deep foundations that are of interest to civil/geotechnical engineering community. The topics cover a wide spectrum of applications that include evaluation of the axial and lateral capacity of piles, pile group effects, evaluation of the increase in pile capacity with time (or pile setup), influence of excavation on pile capacity, study the behavior of pile raft caisson foundations, evaluate the bearing capacity and settlement of piles from cone penetration tests, etc. This volume is part of the proceedings of the 1st GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2017.

Competent deposits of cemented sands distribute extensively along the coastline areas of Western Australia and many other coastline areas worldwide. These soils do not conveniently fall into any specific soil types of sand or clay and there are not yet generally accepted procedures for the design and analysis of piled foundations where lateral loads are comprised predominantly in these soils. In-situ cone penetration test (CPT) provides continuous profile data of the soils in question. Utilizing the cone data for design parameters for the lateral piled foundations has increasingly attracted interests.This thesis investigates the lateral response of single piles in cemented sand and weak rock. The geotechnical behavior of the soils across a wide range from very weakly-cemented sands to well-cemented sands has been studied through a series of laboratory testing programs and in-situ testing programs. Full-scale lateral load experiments were performed with fully instrumented drilled and grout piles in a weak calcareous sandstone deposit at Pinjar, North West Perth in Western Australia. Centrifuge-scale load tests were also carried out on model piles preinstalled in very weakly-cemented sands artificially prepared with varying cement contents. The results of the field test were used to develop the load transfer P-y relationships as well as the limiting transverse pressures Pu on piles for the well-cemented soils. The results of centrifuge model test in conjunction with finite element modelling were used to develop the lateral pressure-displacement P-y relationships and the limiting transverse pressures Pu for the very weakly-cemented soils. The field and centrifuge tests were modelled well using a hyperbolic P-y relationship and the obtained ultimate lateral resistance. Existing methods to estimate Pu and the formulations of P-y curves were also evaluated and conclusive comments made to the comparisons.The thesis then explores the potential of using CPT qc data directly for the design and analysis of laterally loaded piles. A simple CPT-based bi-linear p-y approximation for the lateral response is proposed. This formulation is shown to provide good predictions for lateral pile response in a variety of cemented deposits.

This book presents models that capture the nonlinear response of piles subjected to lateral forces. Utilising a consistent approach encompassing new mathematical models, it offers solutions presented as closed-form expressions and underpinned by the same set of 3-5 measurable soil-input parameters. These focus on nonlinear response of mono piles, anchored piles, pile groups, and torsional piles, as well as passive piles subjected to soil movement induced in shearing, sliding slopes or excavation, and earthquake shaking. The models can also be used for pipelines and similar beam structures. Solutions are provided in the form of design charts, with each parameter obtained using available test data and illustrated with real-world cases. The models reveal, for the first time, the mysterious mechanisms of amplification resulting from back-rotation, which have incurred the collapse of structures such as the Showa Bridge and Nicoll Highway, as well as the distortion of piles during earthquakes. Advanced Design of Pile Foundations Under Lateral Loading is ideal for practicing foundation engineers and students at graduate level. Wei Dong Guo is co-founder of Hans Innovation Group and former Associate Professor at the University of Wollongong, Australia. He is a Chartered Professional Engineer and is a Fellow of Engineers Australia by whom he was awarded the 2012 Warren Medal.
