Liquefaction Evaluation of the CREC Geotechnical Experimentation Site Near Charleston, South Carolina Based on Cone Tests

A geotechnical experimentation site is being developed at the Clemson University Coastal Research and Education Center (CREC) near Charleston, South Carolina. The development of the CREC geotechnical site is part of a three-year research project sponsored by the National Science Foundation on characterization of the liquefaction resistance of aged soils. The site is located on a beach deposit of the 100,000-year-old Wando Formation. Investigations conducted at the site include 3 seismic and 3 non-seismic cone tests with pore pressure measurements. The beach sand is 10 to 13 ft (3 to 4 m) thick. The ground water table is located at a depth of about 3 ft (0.9 m). Field evidence indicates that this beach sand did not liquefy during the 1886 Charleston earthquake. To correctly predict low liquefaction potential at the site based on the cone penetration test data, an age (or deposit resistance) correction is needed. This finding agrees with a recent liquefaction potential mapping study of Charleston peninsula. Because aged soils are common in South Carolina and throughout the world, these findings may have a significant economic impact on the seismic design of bridges and highways
