The current best practice in geotechnical engineering in determining lateral capacity of piles is to replace the soil reaction with a series of independent springs. Basically, the model uses beam theory to represent the pile and uncoupled, non-linear load transfer functions, called p-y curves to represent the soil. Most of the existing methods for determining p-y curves are highly empirical, based on a limited number of cases of laterally loaded piles, which were instrumented, enabling to measure the pile deflection in discrete depth intervals subject to different lateral load (i.e. Matlock 1970, Reese 1975). In essence, these methods have their own limitations, and are mainly applicable for the conditions similar to the tested conditions. Although later, more detailed investigations by different people addressed some of the problems, still the basis of the existing design programs such as LPILE, or procedures introduced in applicable codes such as API (American Petroleum Institute), is the same original recommendations made by Matlock and Reese during seventies. In recent era, demand in employment of in-situ direct-pushed based methods using multi-measurement in-situ devices, such as the seismic cone penetration test with pore water measurement (SCPTu) and Seismic Flat Dilatometer Test (SDMT) is significantly increased. The main objective of this research is to introduce a unified CPT-based approach for determining p-y curves and pile responses to lateral loads. The suggested approach will provide explicit and defined steps/criteria to develop p-y curves for piles subjected to lateral loads using CPT data. CPT data will be used to determine soil strength parameters. Recent developments in relating CPT data to soil basic parameters using Critical State Soil Mechanics (CSSM) framework will be implemented in the suggested model. In all current common models, pre-determination of the soil behavior and the model to be used (e.g. Matlock clay, 1970 or Reese sand, 1975), will become warranted even before commencement of the analysis. On the contrary, in the proposed model, the need for the said pre-determination of soil behavior is eliminated. As discussed in Section 2.3.5, soil behavior in the model is being classified into four broad and general groups: drained-dilative, drained- contractive, undrained-dilative and undrained-contractive The main factor driving the suggested analytical approach is Soil Behavior Type Index, Ic. In the proposed approach, the SBT index, Ic, will be used to determine the in-situ characteristics and behavior of the soil. Based on the value of Ic calculated from CPT data, it could be determined that the soil behaves as a sand-like or a clay-like soil, and during the shearing would behave in undrained or drained condition. The measured shear wave velocity during field test using seismic cone penetration test or other methods such as SASW (Spectral Analysis of Surface Waves) or Cross-Hole logging, may be used to determine the small strain shear modulus, G0, which corresponds to the initial stiffness of the linear part of the p-y curve. In this research, the proposed model will be verified using collected case histories of laterally loaded piles with available CPT data at the same site. The p-y curves, and pile force-head displacements determined from the model will be compared to the field-resulted p-y curves and pile head displacement measurements available from the case histories.

Cone Penetration Testing: Methods and Interpretation discusses the history, applications, and development of the cone penetration test procedures and related test procedures. The book is divided into two parts. Part 1 deals with the cone penetration test proper – its general and historical outline, equipment and their accuracy and calibration, the use of the test results, and its parameters in different kinds of soils and materials. Part 2 covers the role and use of piezocones and its use for the assessment of soil. The text is recommended for engineers and geologists who would like to know more about the applications of the pressuremeter and the interpretation of its results.

This manual presents procedures and guidelines applicable to the use of the cone penetration test. It represents the author's interpretation of the state-of-the-art in Dutch static cone testing as of February 1977. Its contents should provide assistance and uniformity to engineers concerned with the interpretation of the data obtained from such testing. Only geotechnical engineers familiar with the fundamentals of soil mechanics and foundation engineering should use this manual. The manual includes: Introduction and review of the general principals concerning cone penetrometer testing. Individual design chapters which address topics such as: pile design, shear strength estimation, settlement calculation and compaction control; and Appendices which present previously published, pertinent information on cone penetrometer testing.

The objectives of this project are focused on a new cone penetration testing (CPT) geotechnical design manual for highway and transportation applications based on recent research and innovation covering the period from 2000 to 2018. A step-by-step procedure is outlined on how to use CPT data in the analysis and design of common geotechnical tasks. Previous manuals are either very outdated with information from 1970-1996, or not appropriately targeted to transportation works. This design document introduces modern and recent advancements in CPT research not otherwise captured in legacy manuals from the 1990’s and earlier. Examples and case studies are provided for each topic interpreted using CPT measures. In the manual, a step-by-step procedure is outlined on how to use CPT data in analysis and design for typical geotechnical practices. These topics, which are applicable both to state highways and local roads, include bridge foundations (including shallow footings and deep foundations) and soil characterization (including determination of standard soil engineering properties).

This volume contains the proceedings of the 5th International Symposium on Cone Penetration Testing (CPT’22), held in Bologna, Italy, 8-10 June 2022. More than 500 authors - academics, researchers, practitioners and manufacturers – contributed to the peer-reviewed papers included in this book, which includes three keynote lectures, four invited lectures and 169 technical papers. The contributions provide a full picture of the current knowledge and major trends in CPT research and development, with respect to innovations in instrumentation, latest advances in data interpretation, and emerging fields of CPT application. The paper topics encompass three well-established topic categories typically addressed in CPT events: - Equipment and Procedures - Data Interpretation - Applications. Emphasis is placed on the use of statistical approaches and innovative numerical strategies for CPT data interpretation, liquefaction studies, application of CPT to offshore engineering, comparative studies between CPT and other in-situ tests. Cone Penetration Testing 2022 contains a wealth of information that could be useful for researchers, practitioners and all those working in the broad and dynamic field of cone penetration testing.

The "Red Book" presents a background to conventional foundation analysis and design. The text is not intended to replace the much more comprehensive 'standard' textbooks, but rather to support and augment these in a few important areas, supplying methods applicable to practical cases handled daily by practising engineers and providing the basic soil mechanics background to those methods. It concentrates on the static design for stationary foundation conditions. Although the topic is far from exhaustively treated, it does intend to present most of the basic material needed for a practising engineer involved in routine geotechnical design, as well as provide the tools for an engineering student to approach and solve common geotechnical design problems.
