Figure 5.
The panel a presents a section through sample A within the chamber. Wellbore B extends vertically through the sample. Stress actuator C presses against the sample perimeter. Out and inlet valve D provides saturation at one surface, while out and inlet valve E provides saturation at the opposite surface. Plate F supports the sample. An inset presents the cylindrical sample with segmented outer surfaces and a central opening. The panel b presents the circular sample assembly around wellbore B and plate F. Eight stress actuators C surround the perimeter. Out and inlet valves D and E occur at the sample perimeter. A second inset presents separated components of a stress actuator.Central chamber of the GeoTriax triaxial centrifuge cell and its components: (a) sectional view and (b) top view
