Abstract
Recent development in the application of bender element technique has made it possible to measure Gmax, and K0 of soils under complex anisotropic loading conditions. By measuring the shear wave velocities in different shear planes, the anisotropy in Gmax, of soil induced by anisotropic loading can be determined. The shear wave velocities can also be used to calculate the horizontal earth pressure coefficient at rest K0. This paper reports an experimental setup developed at the Department of Civil Engineering, University of Kentucky, which uses bender elements to measure shear wave velocities in four shear planes in a saturated clay specimen under different consolidation pressure. The data is used to investigate the anisotropy of soil stiffness in clay due to anisotropic stress conditions. The measured Gmax is compared with the calculation by several empirical formulae. The measured Gmax on different shear planes are also used to calculate K. of clay under different consolidation pressure and compared with results of empirical theories. The applied stress condition includes loading, unloading, and reloading of up to 22 cycles, thus allowed us to study the influence of repeated loading on Gmax and K0 of clay. The study is funded by the National Science Foundation.
