Evaluation of Elasticity Modulus of Clayey Soil from Undrained Shear Strength

The modulus of elasticity represents the soil stiffness; it was used to design and analyze foundation, slope stability, retaining structure, etc. It is one main input parameters in finite element method for analyzing behavior. scope this study evaluate correlation between (E) cohesion (c u ) remolded undisturbed samples clayey so can assess effect lateral confining pressure on elasticity. unconfined test chosen identify stress-strain After experimental utilized done, modeled using several states soil. PLAXIS program utilized, results are compared with practical results. mohr-Coulomb model because commonly used. Based throughout study, be concluded simulation Mohr-Coulomb software gives good representing compression test, that soft clay, ratio equal (Eu = 30 c clay 55 clay. While stiff 65 120 higher than difference almost double case affects modules soil; however, range drained (5 25 MPa), while undrained (18 54 MPa). Moreover, (11 100 MPa) a an case.
