Determination of Shear Modulus of Elasticity of Soils for Application in Plaxis Model

One of the important parameters of soil properties for application in the Plaxis, to analyse the behavior of earth structures and their failure mechanisms, is shear modulus of elasticity. An intensive geotechnical survey, field and laboratory tests were executed to estimate the values of this parameter and other soil properties in the body of dike and polder. To determine this parameter, 9 different methods were used. Because of large differences among the given values, characteristic values for each layers of soil, were calculated by using a statistical procedure. Then, calibration of stresses and strains were used to verify the characteristic values and appropriate soil test. Both of the calibrations resulted in values more than characteristic values of shear modulus which were close together. The comparison of results of calibrations with foregoing methods showed that the characteristic values were not reliable because of the shortage of data and utilization of triaxial test to determine the shear modulus was better than others.
