Book Description
In this paper, a new true triaxial loading device with mixed rigid and flexible boundaries and its setup are described. The main features of the new true triaxial loading device are four sliding rigid plates acting on the soil specimen enclosed in a rubber membrane, which solves the corner contact interference problem. Measures for reducing friction on the specimen are also presented. All forces and sources of friction on the soil specimen applied by this loading device and their influence on the distribution of strains and stresses in the specimen are analysed and discussed. The true triaxial apparatus with this new loading device has been used to study the stress-strain behaviour of a completely decomposed granite (CDG) soil in Hong Kong. Typical test results are presented and discussed. Based on the description, test results, and discussion, it is found that this new true loading device has a number of merits, especially for testing soils under large strains without corner interferences. It is also found that the stress-strain behaviour of the CDG is dependent on the b-value and the Lade-Duncan failure criterion is more suitable for the CDG in a three-dimensional stress state.

Evaluation of a Three-dimensional Stress Cell for Granular Soils

Book Description
The study presents the results of tests of rigid, solid, spherical, three-dimensional stress cells for measuring the complete state of stress at a point in a soil field under static or dynamic loading. In addition, a theory is presented for defining the behavior of a spherical stress cell embedded in nonlinear materials. The test results indicate that the stress cells are excellent for making static measurements in sand but that their adequacy for dynamic measurements requires further evaluation. (Author).
Advanced Triaxial Testing of Soil and Rock

Book Description
"Although the triaxial compression test is presently the most widely used procedure for determining strength and stress-deformation properties of soils, there have been no books published on triaxial testing since the 1962 second edition of the landmark work The Measurement of Soil Properties in the Triaxial Test by Bishop and Henkel. It is apparent there is a need to document advances made in triaxial testing since publication of Bishop and Henkel's book and to examine the current state of the art in a forum devoted solely to triaxial testing. Because of increasing versatility brought about by recent developments in testing techniques and equipment, it is also important that the geotechnical profession be provided with an up-to-date awareness of potential uses for the triaxial test."--Overview.
The Development of a Three-dimensional Stress Cell for Granular Soils

Book Description
The study presents the results of preliminary tests on a three-dimensional soil stress cell. The results indicate that: (1) The hydrostatic response is linear fr stress up to 3000 psi. (2) The cell requires no calibration. (3) Its response is insensitive to variations in soil stiffness. (4) Its dynamic response closely follows the decay of the overpressure pulse. (5) With a few exceptions, the measured stresses computed from the stress cell data and corresponding stresses in the soil are within 10 percent absolute. More extensive testing and evaluation is required before the stress cell developed can be used with complete confidence. (Author).
