Full-Day Courses

8:00 a.m. - 5:00 p.m.


2D/3D Slope Stability and Seepage for Levee Analysis

Instructors: Murray D. Fredlund, Ph.D., M.ASCE, President and CEO, SoilVision Systems Ltd.; Scott T. Anderson, Ph.D., P.E., D.GE, M.ASCE, Senior Numerical Modeling Engineer (Geotechnical), HDR Engineering, Inc.; John D. Quaranta, Ph.D., P.E., M.ASCE, Assistant Professor, West Virginia University


The design of levees over the past few years has come under increasing scrutiny due to the occurrence of high profile failures such as the levees around New Orleans. The analysis of levee systems in the United States has evolved to a specific methodology which has been determined from a mixture of science and the often litigious process. As new methodologies, science, and computer software become available it is necessary to review design procedures in light of new technologies.


This course examines the application of newer technologies and the traditional methodology of analyses of earth levees by numerical models. The focus will be on aspects of a correct numerical analysis of slopes by the limit equilibrium and finite element methodology. The focus will be on advanced concepts of slope stability analysis and their application. Applications of 3D solutions to real-world problems will be covered.


Risk Assessment in Geotechnical Engineering

Instructors: D. Vaughan Griffiths, Ph.D., P.E., F.ASCE, Colorado School of Mines; Gordon A. Fenton, Ph.D., P.Eng., P.E., A.M.ASCE, Professor, Dalhousie University


Soils and rocks are among the most variable of all engineering materials and are, therefore, highly amenable to a probabilistic treatment. The application of statistical and probabilistic concepts to geotechnical analysis is a rapidly growing area of interest for engineers as indicated by recent new books, journals, and dedicated sessions at practice-oriented conferences. The course content and delivery will assume no more than an introductory understanding of probability and statistics on the part of the participants; however, the goal is to present a, "user friendly," training on modern probabilistic techniques applied to classical geotechnical engineering problems such as seepage, settlement, bearing capacity and slope stability.


The course will inclde:

  • Discussion of potential benefits of probailistic approaches as opposed to the classical "Factor of Safety" methods
  • Review of sources of uncertainty in geotechnical analysis
  • Review of some simple statistical theories needed to develop the methodologies and how to interpret the results of probabilistics analyses
  • Theory behind current geotechnical Load and Resistance Factor Design (LRFD) implementations
  • Explain how LRFD differs from traditional design, and future directions in geotechnical LRFD
  • Examples of established probabilistic methods of analysis in geotechnical engineering, such as, Simple Monte-Carlo (MC) methods, the First Order Second Moment (FOSM) method, and First Order Reliability Methods (FORM)
  • Introduction to numerical methods of probabilistic analysis based on the finite element method, such as the Random Finite Element Method (RFEM)


Testing and Analysis of Piles, and Design of Piled Foundations

Instructor: Bengt H. Fellenius, Dr.Tech., P.Eng., M.ASCE, Consulting Engineer


The current trend in deep foundations is toward larger loads, larger diameter, and longer piles, and the supported structures are becoming more sensitive to foundation deformation. As a result, static loading tests on instrumented test piles are becoming more common, and the practice is increasingly requiring detailed analysis of the test and implementing the analysis results in foundation design. The advanced deep foundation design requires emphasis on load distribution and settlement under service load.


The presentation includes both broad generalities and in-depth details. Basic principles of effective stress analysis are reviewed and correlated to case histories, involving instrumented piles, residual load, and development over time. The pros and cons of the current methods of testing are indicated and the conventional head-down and the O-cell tests are discussed in reference to case histories. Principles of settlement analysis of single piles and small and large pile groups are presented from aspects of load directly on the piles combined with influence from adjacent activity. The design in settling ground and reclaimed land where piles will be affected by drag load and downdrag are emphasized and the "Unified pile design method for capacity, settlement, drag load, and downdrag" is detailed with examples from actual projects. A few aspects are included of construction aspects, as well as, of Load and Resistance Factor Design, LRFD.


Geophysical Methods for Geotechnical Site Characterization

Instructors: Sebastiano Foti, Ph.D., Associate Professor, Politecnico di Torino, Italy; Dennis R. Hiltunen, Ph.D., M.ASCE, Professor, University of Florida; Glenn J. Rix, Ph.D., M.ASCE, Principal Geotechnical Engineer, Geosyntec Consultants; Cesare Comina, Ph.D., Researcher, Politecnico di Torino, Italy


Geophysical tests are widely used in site characterization for geotechnical and geo-environmental applications. A wide spectrum of methods is available to reconstruct geometrical features of the subsoil accounting for different responses of soils as a porous medium and for the characteristics of the pore fluid. Seismic tests provide the advantage of an evaluation of the mechanical response of the medium, although only at very small strain levels, with the possibility of testing geomaterials in their undisturbed state on site. Non seismic methods provide very powerful methods for imaging the subsoil and for monitoring transient processes in geo-environmental applications. The course is intended as an introduction to geophysical tests, but itw ill also provide highlights on current developments and advancement in the state of practice. It will outline the basic principles of different methods, providing information for the correct choice of geophysical tools. Several case histories will be presented and discussed to highlight advantages and limitations of each approach from the perspective of the geotechnical engineer.


Geotechnical Site Characterization: Integrated In Situ Testing, Drilling & Sampling, & Laboratory Testing

Instructors: Don J. DeGroot, Sc.D., P.E., M.ASCE, Professor, University of Massachusetts; Jason T. DeJong, Ph.D., M.ASCE, Associate Professor, University of California at Davis


This short course covers in situ testing, drilling, soil sampling, and laboratory testing for performing site characterization for geotechnical design. Site characterization programs ideally combine in situ and laboratory testing and the pros and cons of both are discussed. The course focuses on best practice methods, including guidance for properly specifying investigation work and for assessing the quality of data obtained. In situ and laboratory test equipment, procedures, and data interpretation methods for determination of soil stratigraphy and soil design parameters such as compressibility and shear strength are described. Example data sets from recent site investigations are presented to illustrate application of the short course concepts. The course is suitable for geotechnical engineering public and private sector practitioners, graduate students, and academics.


Estimation of Rock Properties for Foundation Design

Instructor: Fred H. Kulhawy, Ph.D., P.E., Dist.M.ASCE, Professor Emeritus, Cornell University


Rock property estimation is fundamental to most of geotechnical design. On large projects with relatively generous budgets, the required field and laboratory tests can be conducted to evaluate the necessary geotechnical properties for design. For all other projects, testing will be more limited, and some properties will have to be estimated using correlations. Under the sponsorship of EPRI and others, significant research has been conducted at Cornell to assess rock property correlations in a realistic manner, including the uncertainty in each correlation. In addition, various classification systems have been developed that have become part of the evaluation process, for better or worse. All of these results are scattered widely in the literature.


In this short course, much of this technology is presented within a consistent, coherent, and practical framework so that one can build upon basic geologic knowledge to evaluate the rock mass and estimate its key properties. The general topics covered include the following: basic geologic issues, structural geologic features, rock drilling-core logging-RQD, geophysical exploration, the soil-rock boundary, in-situ stresses, rock mass classification, characterization via Hoek and Brown, rock strength and deformation properties, and uncertainty in basic rock properties.


For this course, comprehensive notes are used that facilitate technology transfer. These include organized copies of the course presentation materials and supplemental readings to provide further details.



Half-Day Courses

Principles of Sustainability in Geotechnical Engineering

Instructors: Anand J. Puppala, Ph.D., P.E., D.GE, F.ASCE, Professor, University of Texas at Arlington; Dipanjan Basu, Ph.D., C.Eng., M.ASCE, Assistant Professor, University of Waterloo


This course will focus on the latest research activities related to sustainability in geotechnical engineering, including utilization of recycled materials and use of alternate materials and construction methods to reduce carbon foot print. The life cycle based methods (LCA, EIA, LCC, etc.) for assessing the sustainability of geotechnical projects will be introduced. A brief introduction to the different sustainability rating systems and their applicability in geotechnical engineering will also be provided. Examples will be given from actual case and research studies so that the attendees can connect the concepts to real life applications.

Geo-characterization for Numerical Modeling

Instructors: Roger Hart, Ph.D., P.E., M.ASCE, Principal Software Advisor, Itasca Consulting Group, Inc.; Augusto Lucarelli, Lead Geotechnical Engineer, Studio Tecnico Associato (SINTESI)


The course will include general guidelines and recommended practices for numerical modeling of geo-structures such as embankments, foundations, deep excavations, etc. The main focus will be on estimation of parameters for soil constitutive models with reasonable number of parameters that can be estimated from in-situ or traditional lab tests will also be discussed along with their applicability. This also includes models to capture the dynamic behavior or soil including liquefaction. Different case studies will be presented to emphasize the importance of using advanced constitutive models for certain scenarios. The importance of soil-structure interaction and estimation of interaction parameters for numerical modeling may also be discussed depending on duration of the course.
