Some Effects of Test Configuration on Measured Soil Properties Under Cyclic Loading
The effects on soil properties measured under cyclic loading of some of the differences between the stress and deformation conditions in cyclic simple shear tests and cyclic triaxial tests are discussed. The importance of differences in the deformation conditions is emphasized. An approximate method is presented for computing the equivalent linear shear modulus of a cross-anisotropic triaxial test specimen. Experimental data on the properties of Monterey No. 0 sand measured in cyclic simple shear and cyclic triaxial tests are presented, and it is shown that in spite of some difficulties caused by the nonlinear behavior of the test specimens it was possible to obtain good agreement between the results of the two types of test.
