CHANCE engineer quantifies what extra helix plates add to pile capacity
Dr. Alan Lutenegger looks at field and lab load tests to show how much axial capacity is gained when a second or third helix is added to a single-helix anchor or pile, in both sand and clay. The post compares tapered and cylindrical helix arrangements and follows an earlier article on single-helix load improvement.
