- Course Outline
The primary intent of the course is to provide information that will enable the attendees to recognize that deep foundation design is a good deal more than finding some value of capacity, and really about deformation and settlement. The course aims to show what data one must pull together and what processes of analysis and calculations that are necessary for a design of a specific project.
The presentation includes both broad generalities and in-depth details. Aspects of how to install instrumentation, perform a test, and analyze the test data are addressed. Settlement analysis is of vital importance to the design of piled foundations and the course addresses the principles of settlement analysis, and some of the mechanics of actually calculating settlement. Some details are included of construction aspects as well as aspects of Limit States Design, LSD (Ultimate Limit States, ULS, and Serviceability Limit States, SLS, by Canadian terminology and Load and Resistance Factor Design, LRFD, by US terminology). Target Audience The target audience for this course includes geotechnical engineers, bridge designers, resident engineers and consultant review specialists. The course embraces both construction and design, participants are expected to have passed an undergraduate course in soil mechanics and/or have successfully completed the Global Innovative Campus (GIC) course on Soils Engineering for Practical Applications. This course is intended for designers, and field or laboratory personnel with a background in engineering. This course is suitable for attendance by entry-level and experienced engineers and advanced-level technicians. In addition, structural, design, and construction engineers, project management and construction engineers in charge of pile-driving construction are encouraged to attend. College and university faculty; consultant engineers and geologists who are involved in pile analysis, design and construction. The course will be most beneficial to geotechnical engineers, engineering geologists, foundation designers, project engineers, and highway/bridge engineers who are involved in the design and construction of foundations for surface transportation projects.
