Vibrocone Data from Paired Soundings at Historic Liquefaction Site,
Thompson Industries, Charleston, South Carolina
Pile Capacity from CPT
• Rational Methods (“Indirect”) to
assess end bearing & side friction
• Direct Methods - Scale up
measured CPT fs and qt to Pile
• Interface roughness effects on
measured sleeve (Frost & DeJong,
2001)  Multi-Friction Sleeve
