In-Situ Geotechnical Tests for Soils
3
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
