Figure 1.
The panel a presents the experimental apparatus beside a 1 metre 75 centimetre human scale reference. The assembly includes a counterweight, flight P C s, an arm, a rotary union, an outlet of the rotary union, a data logger and an experimental payload. A detailed view presents the cylindrical experimental payload with its surrounding components and upper actuator assembly. The panel b presents a cutaway of the payload divided into chamber 1, the upper chamber, chamber 2, the central chamber, and chamber 3, the lower chamber. The panel c provides front and section A-A technical views of the chamber assembly. Section A-A marks chambers 1, 2 and 3 and gives an overall height of 818 millimetres, a width of 650 millimetres, a vertical dimension of 495 millimetres and a lower section dimension of 203 millimetres.Overview of the GeoTriax system and its configuration for centrifuge testing: (a) rendered view of the GeoTriax assembly mounted on the 2 m-radius beam centrifuge at GeoCERF, showing its installation within the centrifuge platform; (b) exterior view with sectional 3D rendering illustrating the main cell body and three-chamber configuration, including the upper loading chamber, central specimen chamber, and lower sand-trap/collection chamber; and (c) 2D cross-sectional engineering schematic showing the internal layout and principal dimensions of the cell
