Installation of Apparatus to Study Weak Rocks of the Maltese Islands

Diogo Teles a QA, Support and Installation Engineer from GDS Instruments, has recently returned from the University of Malta, where he installed an Enterprise Level Dynamic Triaxial Testing System (ELDYN), a 4MPa Triaxial Automated System (GDSTAS) and a High Pressure Triaxial Automated System (100kN / 64MPa / 100mm, HPTAS). High pressure LVDT’s and Acoustic Velocity Transducers have been purchased for the high pressure system. Whilst, Hall Effects, Bender Elements and LVDT’s have been procured to use on either the ELDYN or GDSTAS.

Case Study: Numerical Analysis, Design of Dams (Natural Soils, Tailings) And Deep Excavations

When performing stability tests for the purpose of designing dams and deep excavations, an essential component is the appropriate selection of strength parameters of soils. Due to the fact that on the shear surface we deal with, the principal stress direction rotates, it is important to determine the strength parameters for the compression and the extension loading conditions.
