In-Situ Geotechnical Tests for Soils

In-Situ 2001 - Bali

Specialized In-Situ Tests

– Lateral Stress Cone (LS-CPT)– Cone Pressuremeter (CPMT)– Vibrocone Penetrometer for

Liquefaction– Self-Boring Pressuremeter (SBP)– Iowa Stepped Blade (ISB)– Borehole Shear Test (BHT)– Vision Cone (VisCPT)– Torsional Impulse Shear Device

– Push-in Total Stress Cells (TSC)– Seismic Piezocone Pressuremeter

(SCPMTu)

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 Penetrometer
