Study of Dynamic Response of the Sandy Soil by Cone Penetration Testing.

Abstract: The surface pressure distribution of the probe is introduced and analyzed during Cone Penetration Testing. It seems that the effect of the probe moving through the soil does not cause large pressures that could create a great deal of disturbance to the soil adjacent to the probe. The location and magnitude of the volume strain in soil during disturbance are also mentioned. By analysis, we get the conclusion that strains are localized at the tip of the probe and do not extend very far past the surface of the probe. We also investigate the velocity of the probe, soil density and viscosity which influence the velocity soil grain and volume strain of the soil greatly. All the parameters studied above are important factors to the generation of soil liquefaction. The results are helpful for soil bearing capacity assessment and the effectiveness evaluation for foundation reinforcement. [Copyright &y& Elsevier]
