... For the construction of two large dams, several triaxial test series were executed on the embankment materials. The first material is an altered sandstone and the second a filter material. Several stress paths of loading were tested: extension test, constant mean pressure test, constant stress...

.... They are a natural extension of the standard triaxial devices and provide a much wider variety of stress paths to be investigated or to simulate. This state-of-the-art paper reviews the relevant literature, examines the advantages and limitations of these devices, and discusses some of the difficulties encountered...

... is illustrated by reference to published data describing K 0 , stress path, cyclic loading, and triaxial extension tests. The advantages of the system are summarized. computer control digital controller saturation ramps isotropic and anisotropic consolidation conventional tests triaxial extension...

... and maximum shearing stress to be functions of effective stress state. Consequently, the normalizing parameters vary with stress points along the stress path. An incremental procedure is established whereby normalized stress-strain curves can be obtained. These curves are relatively independent of effective...
