Dilatometer to compute foundation settlement

Sixteen examples demonstrate how the S. Marchetti dilatometer test (DMT) provides soil compressibility data for the rapid calculation of foundation settlements with an average ratio of predicted to actual settlement equal to 1. 18. The examples include sands, silts, clays and organic soils, with settlement magnitudes from 3 to 2850 mm. The settlement prediction method includes the use of the basic, 1-D vertical compression modulus M, with an example calculation using both an Ordinary Method and a Special Method that includes adjusting M for the magnitude of effective stress.
