1. Title: ESTIMATION OF SOIL PROPERTIES FOR FOUNDATION DESIGN

Instructor: Fred H. Kulhawy

Soil property estimation is fundamental to all of geotechnical design. On large projects with relatively generous budgets, all of 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. In recent years, a major study was conducted to assess soil property correlations in a realistic manner, including the uncertainty in each correlation. However, the results of this study are not yet available in traditional types of reference sources such as texts and manuals.

In this short course, much of this technology is presented within a consistent, coherent, and practical framework. General topics covered include the following: soil property evaluation strategy, geologic inference in property assessment, usage of in-situ tests, relative density assessment, in-situ stress evaluation, soil strength evaluation, and deformability estimation.

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.

2. Title: LOAD AND RESISTANCE FACTOR DESIGN OF DEEP FOUNDATIONS

Instructors: George Goble & Jerry DiMaggio

Load and Resistance Factor Design (LRFD) is now being implemented into geotechnical design by AASHTO and other design codes. It is particularly useful in deep foundation design due to the nature of the design problem and because structural loads are now being defined based on factored loads. This course will review the history of the LRFD concept and other currently available codes for deep foundation design. The design process will be discussed to point out the differences between LRFD and Allowable Stress Design and to review modern deep foundation design. Current codes of AASHTO and PDCA will be discussed critically and some foreign codes will be reviewed. A design example will be presented briefly to illustrate the method.

3. Title: AUGERED CAST-IN-PLACE (ACIP) PILES

Instructors: Tracy Brettmann and Rudolph P. Frizzi

The objectives of the course are 1) to identify systems and applicability to ground conditions; 2) present design methodologies and specification procedures; 3) describe installation means and methods; and 4) present field quality control methods and load verification procedures.

4. Title: MICROPILE DESIGN, SPECIFICATIONS, AND CONSTRUCTION: STATE-OF-THE-ART

Instructors (coordinated by ADSC): Tom Armour, Donald Bruce, and John Wolosic

Final Program

This course will offer the most up-to-date information about the design and construction of micropiles with a specific focus on U.S. practice, as well as a broad view of recent international experience. Acknowledged industry leaders from the design, construction, and testing communities will present a wide range of topics intended to provide the attendees with a comprehensive overview of the subject. Specific design problems will be presented and attendees will have the opportunity to apply what they have learned. Course materials will include the FHWA's Micropile Design and Construction Guidelines Implementation Manual.

5. Title: SIGNALS AND INVERSION IN GEOTECHNICAL SITE CHARACTERIZATIN

Instructors: Glenn J. Rix and Carlos Santamarina

This course presents basic signal processing methods which are commonly employed in geotechnical site characterization including cross correlation, convolution and noise control with time domain and frequency domain operations. Inversion methods which allow the recovery of material properties and the spatial distribution of materials from geophysical observations are also presented. Site characterization with surface waves is emphasized including equipment and field testing procedures, dispersion and attenuation analyses, and inversion methods to obtain the shear wave velocity and shear damping ratio profiles are covered. Other applications discussed in the course include cross-hole and down-hole testing, tomographic imaging, laboratory testing (resonant column and bender elements), and additional nondestructive testing procedures.

6. Title: Computer Software for Design and Analysis of Deep Foundations

Instructors: Frank Townsend, Brian Anderson, Mohamad Hussein, and William M. Isenhower

Summary: This technical short course will present and demonstrate state-of-the-art computer software used in the design and analysis of deep foundations. Over the past 35+ years major changes have occurred in the deep foundations industry. New and improved methods have been developed for installing larger driven piles and drilled cast-in-place shafts to higher load bearing and lateral support requirements. This short course includes presentations on the principles, application, and limitations of modern computer analysis methods. The following programs will be discussed and demonstrated:

1. GRLWEAP, WEAP - programs for wave equation analysis of pile driving.
2. SPT97, DRIVEN, APILE, TZPile - programs for axial capacity of driven piles.
3. SHAFT98, SHAFT - programs using FHWA method for axial capacity and settlement of drilled shafts
4. FLPIER, FB-Pier, GROUP - programs for analysis of axial and laterally loaded of pile/shaft groups.
5. LPILE Plus, COM624P - programs for analysis of individual piles subjected to lateral loading.
6. PYWall - program for analysis of drilled shaft retaining walls.
7. Use of the finite element method for analysis of soil-structure interaction.

Geotechnical, structural, and construction engineers involved in deep foundations design, construction, testing, and/or quality control will benefit from attending this seminar presented by distinguished experts in the field. The presentation will be a computer laptop workshop using example problems. The audience is invited to bring their laptops. We will provide each student a CD-ROM of demonstration for the course. Commercial software used for demonstration will have limited capabilities.

7 Title: Non-Destructive Testing of Bored, Driven and Augercast Piles

Instructors: DFI Drilled Shaft Committee

Summary: The purpose of this Short Course is to present available methods of evaluating the capacity and integrity of the foundation element and load-carrying strata. In addition, the program is designed to aid the end-user with the proper selection and application of the test method and with the interpretation of the results.

The Deep Foundation Institute recognizes the need for clarity in this aspect of foundation engineering and construction, understanding the mis-uses of many test methods in this relatively young segment of the Industry.

The short course includes presentations of the following load capacity test methods:

• Static Load Tests
• Rapid-High Strain Load Tests
• High Strain Dynamic Load Tests.
• Up-Down Load Test.

In addition, the program covers the following pile integrity testing methods:

• Cross-Hole Sonic Logging
• Single-Hole Sonic Logging
• Impulse-Echo Testing

Finally, the importance of proper subsurface investigation, observations during construction and engineering judgment will be emphasized for consideration with the appropriate pile integrity test to determine the viability of the foundations, and means of remediation will be addressed.
