How can I determine the young modulus E50 and soil density from Triaxial test results?

02 May 2018 1 3K Report

I have the results from triaxial test that I will use to model the test in PLAXIS. But I need to determine the relevant parameters such E50 and the density while the Friction angle and cohesion are known.

Young's soil modulus, Es, may be estimated from empirical correlations, laboratory test results on undisturbed specimens and results of field tests. Laboratory tests that may be used to estimate the soil modulus are the triaxial unconsolidated undrained compression or the triaxial consolidated undrained compression tests

Es = KcCu

where: Es = Young's soil modulus (tsf) Kc = correlation factor (http://www.geotechnicalinfo.com/elastic_modulus_constant.pdf) Cu = undrained shear strength, tsf
