Effect of Shaking History on the Cone Penetration Resistance and Cyclic Strength of Saturated Sand

Abstract: The effect of shaking history on cone penetration resistance, cyclic resistance ratio, and their correlation to each other for saturated sand is examined using centrifuge model tests. Prior laboratory and centrifuge modeling studies have shown strain history can have a strong effect on the cyclic strength of sand, but data describing how these effects track with cone penetration resistance are lacking. The effects of shaking history on cone penetration resistance and cyclic strength are investigated using cent… Show more

“…A CaCO3 percentage of 2.2% decreases the actual void ratio by approximately 0.06, which implies an increase in the DR from 38% to approximately 60% (computed using emax and emin for untreated sand). The minimal change in qc observed here is consistent with work presented by Darby et al 2017, whose previous centrifuge tests of uncemented Ottawa sand models suggest smaller qc increases in denser models subjected to multiple shaking events as compared to loose models.…”

“…The smaller model size limits the number of sensors that can be used, increases the effects of boundary conditions, increases the role of partial drainage during shaking, and increases the curvature of the g-field during spinning. Experience with similar studies for uncemented sands has shown that tests on the 9-m radius centrifuge produce significantly higher quality data and resolution than is possible on the 1-m radius centrifuge (Darby et al 2016(Darby et al , 2019. Thus, the results of these more economical, small centrifuge model tests have demonstrated that the experimental and analytical approaches used in the present study have the potential, when extended to larger-scale experiments, to support development of liquefaction evaluation procedures for bio-cemented sands.…”

“…High cyclic strengths, CRRs exceeding 0.6, were developed in both of the silts tested through densification from accumulated post-cyclic reconsolidation strains resulting from multiple cyclic shearing events, suggesting that large cyclic strengths can progressively develop in situ from repeated earthquake shaking events over geologic time. The strength increases associated with single events were, however, relatively modest and consistent with centrifuge test observations by Darby et al (2016) and El-Sekelley et al (2016) for sands. The cyclic strength increase per event was smallest for looser sands and greater for dense sands.…”
