Book Description
Driven piles are commonly used in foundation engineering. The most accurate measurement of pile capacity is achieved from measurements made during static load tests. Static load tests, however, may be too expensive for certain projects. In these cases, indirect estimates of the pile capacity can be made through dynamic measurements. These estimates can be performed either through pile driving formulae or through analytical methods, such as the Case method.Pile driving formulae, which relate the pile set per blow to the capacity of the pile, are frequently used to determine whether the pile has achieved its design capacity. However, existing formulae have numerous shortcomings. These formulae are based on empirical observations and lack scientific validation. This report details the development of more accurate and reliable pile driving formulae developed from advanced one-dimensional FE simulations. These formulae are derived for piles installed in five typical soil profiles: a floating pile in sand, an end¿bearing pile in sand, a floating pile in clay, an end¿bearing pile in clay and a pile crossing a normally consolidated clay layer and resting on a dense sand layer. The proposed driving formulae are validated through well-documented case histories of full-scale instrumented driven piles. The proposed formulae are more accurate and reliable on average than other existing methods for the case histories considered in this study.This report also discusses the development of a pile driving control system, a fully integrated system developed by Purdue that can be used to collect, process, and analyze data to estimate the capacities of piles using the Case method and the pile driving formulae developed at Purdue.

Design of Pile Foundations
Author: US Army Corps of Engineers
Publisher:
ISBN: 9781410219459
Category : Technology & Engineering
Languages : en
Pages : 200
Book Description
This manual provides information, foundation exploration and testing procedures, load test methods, analysis techniques, allowable criteria, design procedures, and construction consideration for the selection, design, and installation of pile foundations. The guidance is based on the present state of the technology for pile-soil-structure-foundation interaction behavior. This manual provides design guidance intended specifically for the geotechnical and structural engineer but also provides essential information for others interested in pile foundations such as the construction engineer in understanding construction techniques related to pile behavior during installation. Since the understanding of the physical causes of pile foundation behavior is actively expanding by better definition through ongoing research, prototype, model pile, and pile group testing and development of more refined analytical models, this manual is intended to provide examples and procedures of what has been proven successful. This is not the last nor final word on the state of the art for this technology. We expect, as further practical design and installation procedures are developed from the expansion of this technology, that these updates will be issued as changes to this manual.

Model Uncertainties in Foundation Design
Author: Chong Tang
Publisher: CRC Press
ISBN: 0429655959
Category : Technology & Engineering
Languages : en
Pages : 497
Book Description
Model Uncertainties in Foundation Design is unique in the compilation of the largest and the most diverse load test databases to date, covering many foundation types (shallow foundations, spudcans, driven piles, drilled shafts, rock sockets and helical piles) and a wide range of ground conditions (soil to soft rock). All databases with names prefixed by NUS are available upon request. This book presents a comprehensive evaluation of the model factor mean (bias) and coefficient of variation (COV) for ultimate and serviceability limit state based on these databases. These statistics can be used directly for AASHTO LRFD calibration. Besides load test databases, performance databases for other geo-structures and their model factor statistics are provided. Based on this extensive literature survey, a practical three-tier scheme for classifying the model uncertainty of geo-structures according to the model factor mean and COV is proposed. This empirically grounded scheme can underpin the calibration of resistance factors as a function of the degree of understanding – a concept already adopted in the Canadian Highway Bridge Design Code and being considered for the new draft for Eurocode 7 Part 1 (EN 1997-1:202x). The helical pile research in Chapter 7 was recognised by the 2020 ASCE Norman Medal.
