Description

Description:

Pile foundations are the part of a structure used to carry and transfer the load of the structure to the bearing ground located at some depth below ground surface. The main components of the foundation are the pile cap and the piles. Piles are long and slender members which transfer the load to deeper soil or rock of high bearing capacity avoiding shallow soil of low bearing capacity. Depending upon type of soil, pile material and load transmitting characteristic piles are classified accordingly. In this workshop participants will learn about, classifications, functions and pros and cons of piles design and construction.
This course provides participants with specific technical guidance on aspects of designing, installing, and the construction of piled foundations.
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), dynamic driving formulas, wave equation analysis, dynamic testing), static methods of pile load testing. Application and interpretation of the wave equation and dynamic and static pile-load-testing methods are highlighted with an emphasis on the practical issues related to pile monitoring and acceptance on typical construction projects. Construction material includes pile capacity verification by formula; wave equation; dynamic test or static test; performance and interpretation of compression, tension, and lateral load test; load testing devices; the Osterberg Cell and Statnamic.

Learning Outcomes:
Upon completion of the course, participants will be able to:

Implement a systematic plan for the design and construction of 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 pile types
Use appropriate methods of pile foundation design in application subsurface conditions
Calculate single and group capacities of 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

Instructor
Dr. Gamal Abdelaziz, P.Eng, MSc. has a Ph.D. in Geotechnical Engineering from Concordia University, Montreal, Canada. Currently he is a senior geotechnical engineer with Global Engineering , Edmonton , Alberta , Canada and adjunct professor at Ryerson University, Toronto, Ontario. Dr. Abdelaziz has served as a senior geotechnical engineer at DST Consulting engineers, Sarafinchin Consulting, Trow Consulting and EBA engineering. He has over 25 years of experience in geotechnical and structural engineering, foundation design, teaching, research and consulting in Canada and overseas.

Dr. Abdelaziz is a former adjunct professor at University of Western Ontario, London, Ontario, Canada, visiting professor at Ryerson University, Toronto, Canada and part time professor at Seneca College, Toronto, Canada. Dr. Abdelaziz is specialized in numerical modeling for solving sophisticated geotechnical engineering problems with respect to pile foundation and the linear and nonlinear analysis of soil-structure interaction. He designed charts to predict pressures acting on tunnels, and developed analytical model for pile bearing capacity prediction. Dr. Abdelaziz authored a number of technical papers and delivered numerous internal and external workshops on various geotechnical and Municipal engineering topics, and they are very well received by practitioners. Dr. Abdelaziz has been involved in a number of projects in Canada and overseas, such as tunnelling, silos, buildings, retaining structures, siphons, irrigation networks and many other civil engineering projects in terms of design and construction. Dr. Abdelaziz is a member in different professional societies such as APEGGA, PEO, CGS, CDA, TAC and ABPA. He is also a reviewer for the Canadian Geotechnical Journal.
