DESCRIPTION:
This course covers the practical application of driven pile technology, with an emphasis on data interpretation and decisionmaking issues common to real-life construction projects. The course addresses subsurface investigation, pile selection, economic analysis, static design analysis (single pile and pile group behavior under compression, tension and lateral loading, pile settlement, negative skin friction) specifications and contracting documents, construction monitoring (pile inspection, dynamic driving formulas, wave equation analysis, dynamic testing), static methods of pile load testing, driven pile installation equipment, and accessories. The course also covers design procedures for subsurface conditions; the computer program for calculating static pile capacity; design procedures for downdrag, scour, squeeze, and heave; plugging of open pile sections; group design for lateral and uplift loads; and the economics of pile selection. Instructional methods include workshops, participant exercises, and sample problems to transfer the necessary knowledge and skills to plan and design driven pile foundation projects and to implement QA/QC procedures during construction. OUTCOMES:
Upon completion of the course, participants will be able to:- Implement a systematic plan for the design and construction of driven pile foundations
- Select appropriate subsurface exploration procedures and laboratory tests to provide design soil parameters for pile foundation design
- Choose the appropriate pile type in a given soil profile based on the advantages and disadvantages of common driven pile types
- Use appropriate methods of pile foundation design in application subsurface conditions
- Calculate single and group capacities of driven piles to resist compression, tension, and lateral loads
- Use time-dependent soil strength changes in pile foundation design and construction control
- Identify the project influence and significance of pile driveability, pile refusal, and minimum and estimated pile toe elevations
- Calculate allowable design and allowable driving stresses for common pile types
- Explain the key differences between allowable stress design and load and resistance factor design methods
- Define key components of driven pile specifications
- Identify the format and minimum content in an adequate foundation report for driven pile foundations
- Use dynamic formulas, wave equation analyses, dynamic pile testing and static load testing correctly and effectively
- Identify pile hammer types, their operational characteristics, and key pile hammer and pile hammer accessory inspection issues
- Select pile toe accessories, pile splicing methods, and pile installation aids applicable to the pile type and subsurface conditions
- Explain appropriate methods of pile installation inspection
TARGET AUDIENCE:
The target audience includes geotechnical specialists, bridge engineers, construction engineers, and consultant review specialists. This course is suitable for attendance by entry-level and experienced engineers and advanced-level technicians. Attendees should have a basic knowledge of subsurface investigation methods and the general aspects of foundation design and construction. |
