Helical piles/anchors have been utilized in uplift forces applications for many years. More recently, they have gained popularity for bearing load applications. The speed and ease of installation, as well as low cost for new construction and repair, make them versatile for many applications.
This course focuses, in detail, on the basic fundamentals of helical piles and the different design theories for piles subjected to axial and lateral loads. In addition, it explores the most recent advances for helical piles subjected to seismic and machine loads. Types of helical piles, installation methods, and effect of geometrical configurations on their performance and capacity are discussed. A thorough treatment of the different field testing programs (i.e. static and cyclic axial and lateral loading) is provided together with a brief description on the instrumentation techniques. Most recent advances in the construction and performance of square-shaft small diameter piles as well as the circular-shaft large diameter piles are presented.
To provide the participants with adequate knowledge on the general principles and theories of helical piles as a versatile pilling technique.
