Unformatted text preview: vertical stress and empirical correlation. o Soil type estimate based on 1 and Eo (really a function of permeability). o Correlate 1-0 tangent modulus, M, to Eo. o Correlations available for OCR, ~', and co. o Can measure pressure P2 at end of test when membrane returns to initial position - provides estimate of insitu water pressure. Repeated P2 measurements can develop a pore pressure decay curve for rough estimate of c. ... o Material Index = I D = (p,-Po) (Po- u o ) p-u o Horizontal Stress Index = K o := 0, 0 0, o Dilatometer Modulus ~ lED = E 2 = 34.7( p, - Po) I (1-~ ) o Good profiling tool. Very repeatable. Lots of data. Primary measurements are stiffness and lateral stress....
