GDS Case Study: Cadia Valley Operations Northern Tailings Storage Facility Embankment Slump

During the afternoon of the 9th of March 2018, a mobile slump occurred in an approximately 300 m section of the southern embankment of the Cadia Valley Operations (Cadia) Northern Tailings Storage Facility (NTSF), located in central-west New South Wales, Australia. The embankment slump resulted in a release of tailings from the NTSF, with the released tailings captured within the adjacent South Tailings Storage Facility (STSF).

Electromechanical Dynamic Cyclic Simple Shear Confined Apparatus

GDS’ NEW Electromechanical Dynamic Cyclic Simple Shear Confined (EMDCSS-CON) is the premier device for simple shear testing. It is capable of carrying out dynamic cyclic tests ranging from small strain (0.005% shear strain amplitude) to large strain (10% shear strain amplitude), as well as a large range of extremely accurate quasi-static testing.

Constant Normal Stiffness Testing Included as Standard in EMDCSS From 2021 (Upgrades Available on Existing Systems)

Testing in Constant Normal Stiffness (CNS) conditions have been widely used to better represent the effects of soil contraction/dilatation on the normal stress at the interface between the soil and the piles. A new (2021) upgrade to the control system and the firmware of GDS’ Electromechanical Dynamic Cyclic Simple Shear Device (EMDCSS) allows the apparatus to perform both static and dynamic simple shear tests in CNS conditions.
