Power Pole Foundations in Reclaimed Mining Area

by Kou-Roung Chang, CH2M Hill, United States,

Document Type: Proceeding Paper

Part of: Foundation Engineering: Current Principles and Practices


In central Florida, where strip mining for phosphate ore is a primary industry, street surfaces often become rolling because of differential settlement, and electrical transmission poles often tilt because of inadequate lateral support. This paper discusses the field exploration, engineering analyses, and construction observation and quality control performed for the densification and replacement of foundation soils for thirteen 230-kV transmission poles through a reclaimed strip-mining area near Lakeland, Florida.
