    • Abstract
  • This paper studied the relationship between penetration resistance or torque and penetration speed, the geotechnical parameters of the mechanical properties, through establishing the mathematical model with the mechanical analysis of the double helix probe. Combined with mathematical models and experimental data, the factors on the impact of the penetration technology are analyzed. The conclusion may afford theoretic basis for designing the probe structure and understanding the mechanic mechanism of the penetration technique.
