Penetration resistance in sands: analysis and applications to liquefaction potential assessment and estimation of pile base resistance



Calibration chamber tests provide an effective way to study cone penetration resistance in sands under controlled conditions. A calibration chamber test is performed in a large sand sample that has been prepared at a known density, consolidated to desired stresses, and subjected to known boundary conditions. Results from calibration chamber tests can be used to verify the relationship between cone resistance, soil density and stress state. In this paper, a penetration resistance analysis recently developed is testcd by comparing its predictions with penetration resistance values measured in calibration chambers. The analysis is shown to predict penetration resistance very well. Applications of the analysis to pile design and liquefaction potential assessment are briefly discussed.
