Comparison of DMT- and CPT-Correlated Constrained Moduli in Clayey and Silty Sands
This paper compares constrained modulus and related data from a geotechnical engineering investigation of a 40,000 m2 site in the Southeastern United States that lies within the Atlantic Coastal Plain. This study includes 47 cone penetration tests (CPTs and SCPTs) and 13 flat-plate dilatometer tests (seismic and nonseismic DMTs) and more than 80 incremental and constant rate of strain consolidation tests. This paper compares the CPT- and DMT-correlated constrained moduli and laboratory test results from co-located borings. The comparative analyses show major differences and key similarities in the correlated values; sources for these differences and similarities are discussed. This paper concludes that in contrast to the DMT, CPT/SCPT soundings and often laboratory consolidation testing underestimate key settlement parameters because of disturbance. Correlations for the investigated soil types are also presented.
