LABORATORY OF PHYSICAL AND MECHANICAL PROPERTIES
Several insights in the processes that govern margin hydrogeology and offshore geohazards can be earned from measurement of physical and mechanical properties on marine sediment samples. The BCSI hosts a physical and mechanical properties laboratory that includes the following equipment:
- A Triaxial Automated System from GDS Instuments. This system is a 50 kN load frame-based triaxial testing system, The system can run advanced tests such as stress paths, slow cyclic and K0, all under PC control. Two 200cc/2MPa advanced pressure/volume controllers are used to apply cell pressure, back pressure, and also to measure the sample volume change resolved to 1cc. The triaxial test is used to determine the stress-strain-strength characteristics of sediments.
- A fully-automated Consolidation Testing System from GDS Instuments specially designed for marine sediments based on the Rowe & Barden cell. The system can run from classic tests such as stepped loading to more advanced tests such as automated testing rate by controlled hydraulic gradient or cyclic loading, all under PC control. The Rowe & Barden consolidation cell can be used with either a rigid porous disk for constant strain or flexible porous disk for constant stress. The cell incorporates a Bishop and Skinner floating ring, which allows the top bag to move with the specimen vertically, thus it allows measurement of the upper chamber volume change to be used as a calculation of axial strain.
The system uses three 200cc/2MPa advanced pressure/volume controllers that link the computer to the test cell as follows: 1) for axial stress and axial displacement control, 2) for setting back pressure and measuring volume change and 3) for applying base pressure to the sample to derive true Darcian permeabilities. This system allows to characterize the sediment stress-strain behaviour during one-dimensional compression attempting to simulate the process of sediment burial and sample porosity reduction.
